Episode : Ecosystems

00:00:00 - Hello everyone. We are very excited today because we are going to talk about a topic that it's very interesting for for us to and

00:00:11 - We have been studying it

00:00:16 - The last month and I think it's it's very very interesting. So they are

00:00:22 - I am here with with Liz to talk about the ecosystems. So

00:00:26 - So, first we have to understand what ecosystem is.

00:00:33 - Ecosystem is made of organisms and physical environment and the interactions of the living and non-living components that enable them.

00:00:46 - This concept of ecosystem refers to this place that involves animals, plants and all

00:00:56 - These living beings are not living beings and ecosystems are all around the planet.

00:01:03 - But this ecosystem is related with other concepts that is biodiversity.

00:01:11 - The biodiversity is the variety of flora and fauna that existed in the ecosystem.

00:01:19 - So the cause of the ecosystem with the biodiversity give us a result of biosphere. Biosphere is the part of the planet inhabited by organism. What refers to this? It refers to to the cause of the biodiversity and the ecosystem.

this is the vessel between these two concepts. So in this biosphere we find these other two concepts that are the biotic components and the abiotic components.

00:02:04 - The biotic components are the living part of an ecosystem. I am referring to plants, to animals and all living beings on an ecosystem. And then we have the abiotic components that are the non-living part of an ecosystem. And I am talking about, I don't know, maybe rocks or a river, the water, the humidity. These are the abiotic components. And I would like to introduce to my partner Luis.

00:02:35 - He is going to talk about more about these two concepts.

00:02:45 - Yes.

00:02:46 - Well, thanks, Jordan.

00:02:48 - When we were talking about the components of an ecosystem, it is important to know what are the biotic components.

00:02:56 - And well, as Jordan said, the biotic components are the linked parts of an ecosystem.

00:03:03 - More specifically, the biotic components are the community, the animals, the plants, and the organisms that are in an ecosystem.

00:03:15 - And the biotic components can be, well, we can say that those are the components that can be measured, like the air, the wind, the water, the humidity, the oxygen concentration, the temperature, and that kind of thing.

00:03:37 - Well, when we're talking about the necrosis stem, and more specifically about the biodiversity, it is important to know about the population interactions.

00:03:50 - The population interactions are, when we know winter,

00:03:56 - There are more than one organism interacting with other, and the first kind of population interaction is a competition.

00:04:07 - When an organism in an ecosystem has some effect on any other organism, and there are two kinds of competitions.

00:04:15 - The inter-specific competition, which is the competition between members of the same species, and the interspecies, which is basically a competition between members of two different species.

00:04:32 - Jordan, could you give us an example of competition?

00:04:38 - Yes, for sure. I would like to do that. An example could be lions and hyenas.

00:04:45 - The genus competes for food and for the dead body that had been already eaten by the lions.

00:04:54 - When two species compete for something, this is the definition of competition.

00:05:03 - Now I'm talking about the lions and the genus that competes for food.

00:05:11 - This is a good example for competition.

00:05:13 - Well, there are other population interactions, like the parasitic system, and it is basically a relationship for one organism, in this case the parasite, benefit from other, and this relationship derivates in both for the parasite.

is also the predation when an animal sometimes a plant it's another animal and well Jordan could you give us another example of this case of predation? Yes I would like to talk about the dogs and the ticks this is a very common example

00:05:57 - So, pigs usually get in the dogs and then just feed from their blood.

00:06:08 - The definition of parasitism is when a species establish a colony or in another living being, in this case the other living being are the dogs.

00:06:22 - Well, and the last example of a population interaction is the sign just.

00:06:31 - And it is the interaction where both organisms are benefited.

00:06:36 - An example could be the algae and the corals.

00:06:41 - Well basically the corals provides the algae with nutrients and the algae provides the corals with oxygen and food.

00:06:52 - So Jordan, we will tell us how the abiotic components are measured.

00:07:01 - Yes, in this case, I would like to talk about three different situations in which we can measure the abiotic components.

00:07:17 - I will talk about the marine, the terrestrial, and the freshwater.

00:07:22 - So in the fresh water, we can measure the turbidity, the low rate temperature, and the oxygen dissolved on the water.

00:07:36 - On the terrestrial, we can measure the soil moisture, the wind of the speed, the mineral content, the temperature and the like intensity. In the marine, we can measure the salinity,

00:07:55 - For example, the soil.

00:08:15 - Well if we want to comprehend this, it is important to have an example and this is an an example that fascinates me and for this I would need you to visualize the next thing.

00:08:30 - We are in the Philippines and we are in our rainforest.

00:08:33 - If we wanted to identify five biotic and five abiotic components we could say that the biotic components could be the turtles, the birds, the lizards, maybe an endemic species like the Philippine eagles, and the aphiotic components could be maybe the soil, the sun, the wind, the humidity, and, well, the oxygen levels.

00:09:03 - And, well, it is important to note that there is a strong bond between the biodiversity and the ecosystem because creatures must adapt to be able to survive with the available resources in an ecosystem and if you affect available resources in that ecosystem the creatures will not will not be able to adapt to such situation in a short period of time.

00:09:39 - Well there's something I want to talk about and that's the difference between food chain and the trophic levels. Well, I've heard many people that are confused and many people think that the food chain and the trophic level are the same, but well it is not the same and well the food chain is basically a flow of energy that goes from one organism to another and it could be said that it is the relationship between species in an ecosystem.

00:10:18 - And the traffic level is the position that an organism or group of species occupies in a food chain.

00:10:27 - Well, Jordan, could you explain a little bit more further this concept of the traffic level?

00:10:33 - Yes, yes. Also, the trophic level is something that likes me more than the food chain, so

00:10:41 - I will enjoy explaining this. The trophic level is divided in different concepts. The trophic level usually starts with primary producer and ends with carnival.

00:11:01 - So the producer can be a plant that gets energy from the sun.

00:11:05 - Then the autotroph parts are the ones that create their own food from CO2 and H2O, using energy from the sun also like the plants.

00:11:19 - And then we have the consumers that obtain the energy from the autotrophs.

00:11:26 - And then, last, we have the chemo-synthetic organisms.

00:11:29 - And I think these organisms are very, very amazing because they create their own foods from other components, such as ammonia and metanide.

00:11:43 - And I think this capacity of food, their own food, it's just amazing.

00:11:50 - So I think we have been talking for a long time about ecosystem and all the important parts of this topic.

00:12:01 - And I think it's wonderful because it's something very interesting and it's something that is around of all of us.

00:12:10 - And I think we have never put attention to this.

00:12:17 - And I think it takes some time to talk about this environment that is all around of us.

it's important.

00:12:26 - So I think that everyone that have the opportunity to hear this, I hope that like this project because it's something very important for us and we have enjoyed it to do it a lot.

00:12:43 - It's something that Julius would like to say to our audience to say goodbye.

00:12:50 - Well, first of all, I would love to thank you this opportunity. It's been a pleasure to be in this podcast today and well if I wanted to say something to the audience, to the people who are listening to this podcast right now, I would say that you should study more about biology. It is a fascinating topic and I really love the biology and what else can I say?

00:13:20 - It is amazing. So, sorry about biology. Thanks for the opportunity today.

00:13:28 - Thank you.

00:13:32 - Thanks to you.

00:13:37 - So, bye everyone. I hope you care for the next project.

00:13:41 - Thanks.
