BRIAN KILMEADE, CNN: We all know the term ecosystem is a good description for what we’re talking about here.
The idea is the ecosystem is the network of ecosystems.
We have a lot of them.
The most important one is the human body.
It’s a whole different animal than a fish.
It has a whole host of different organs.
And they all work together, so the idea of the ecosystem isn’t just the ecosystem itself.
It is a whole system that exists to keep all of those organs functioning and all of that living things alive and healthy and flourishing and making all of this happen.
That’s how the word ecosystem is applied in the sense of a whole set of interconnected systems, or ecosystems, which are, you know, the organisms in all of these systems that you’re talking to.
The word ecology is more specific.
It refers to a specific set of things that have evolved over time.
The first thing that happens in the ecosystem that you discover is that the bacteria, which live in the soil and live on the surface of the soil, they can take up oxygen, they’re able to metabolize that oxygen, and the organisms that live on those surfaces are able to utilize that oxygen.
They’re able — in fact, they thrive.
They thrive because of the oxygen, because they’re metabolizing it, because of what they’re doing in those surfaces.
They produce carbon dioxide and hydrogen, and they can even capture the carbon dioxide.
But the question is, are they doing all of the things that are needed to support all of their life?
Or are they being left to their own devices?
And we’ve got to find out.
You can’t rely on the oxygen they’re taking up, you can’t depend on the nutrients that they’re being able to absorb.
You have to look at what’s going on in the environment to figure out how to make sure that the organisms are not doing those things that they need to do to survive.
So, the ecosystem system is all about the bacteria.
So the way you describe that is the microbiome, the human microbiome.
And there’s a very important distinction to make here.
In a microbiome you have to separate out different organisms.
There are some bacteria that are not going to thrive in the way that a fish or a treefrog is going to survive in a desert environment, but they’re there and they’re very important.
And some are going to be important in the production of certain compounds in the food they’re eating.
But you also have some bacteria like these microbes that are important for the maintenance of certain ecosystems in the human diet.
And so the way to describe the human microbiota is that they have a way of interacting with each other and with each of the other microbes in the system.
So you have different species of microbes in different environments that are interacting with the human population, and you have bacteria that make a difference in that process.
So we have some human species, which you may have encountered in your daily life, that have been exposed to certain chemicals, and there’s certain bacteria that can help these chemicals stay in the blood stream.
But some of these are going for a walk or a run and there is a different group of bacteria that do not need any kind of chemical to be there.
So these different kinds of bacteria and these different populations of bacteria can help the human species to function and produce certain compounds.
Now, if we look at the human ecology, we can say that, yes, there are certain types of bacteria.
Some of them are essential for the human life.
Others, like the bacilli, which is an important component of the immune system, can help us survive infections and to recover.
And then there are some species that we can eat, and some of those can be helpful in the digestion of certain foods.
So those are all important components of the human system.
But, you also can have some types of organisms that are harmful to the human organism.
And these kinds of organisms, you have seen, can make certain compounds and can harm the human health.
So there’s some sort of a balance that we need to maintain between those two.
And the ecosystem definition is the way in which we describe that balance.
So what we call it in this sense is the concept of ecological systems.
It means that there is something going on that supports the survival of the organism that we’re living in.
And that includes the organisms themselves.
So in the ecology of a species of organism, you need to understand what’s happening in the life of the organisms.
And in the evolution of an organism, we need information about how that organism functions, so that we know what kinds of things are going on.
The information we need is information about what the organisms need to survive and what they need the environment for.
So ecological systems are a kind of a combination of these two concepts
