Transcript

00:02 For this question, we have a few parts.

00:04 The first part is, what is biological hierarchy? biological hierarchy is the organization of organisms and the levels of complexity.

00:19 So it is increasing levels of complexity encompassed within larger groupings.

00:45 And then our second part is how are communities and ecosystems different? well, communities are the...

00:52 The set of populations in an area, and an ecosystem is a community plus the environment.

00:58 So ecosystems include communities, but communities do not include ecosystems.

01:27 Our third part is what is the fundamental evolution or fundamental unit of evolution? so the fundamental unit of evolution would be the population.

01:40 Evolution is the change of the gene pool of a population over several generations.

01:44 So the fundamental unit of your evolution would be population.

01:49 Our next section is what is the foundational level of trophic levels? so the foundational level of trophic levels would be producers.

02:00 That's the bottom of your food chain.

02:02 So that's the foundation level.

02:03 It's your producers.

02:07 Next part.

02:08 What is a trophic level defined by? so trophic levels are defined by the position of an organism in the food chain.

02:16 So it will include all of the following...
