Let's discuss trophic levels.
00:03
So a trophic level is the feeding position of an organism in a specific ecosystem.
00:11
Food chain is a popular example as well as a food web, because that's a little more complex.
00:17
But a lot of people draw the traffic levels as a pyramid, and it can be up to five levels.
00:26
So the first trophic level is going to be primary producers, plants and algae.
00:37
So they are going to be organisms that create their own food, usually by photosynthesis.
00:46
Next will be the primary consumers, the herbivores.
00:52
They are the ones that eat the primary producers, the plants and algae.
00:56
So most insects, cows, pigs, deer, lots of things.
01:01
Things.
01:03
The secondary consumers are going to be those that eat the primary consumers.
01:12
It's a special type of carnivore.
01:14
So we use a cat as an example.
01:16
A cat is an obligate carnivore.
01:18
They will only eat meat.
01:21
So cats, you always pair them with eating mice.
01:23
The mice are going to be the primary consumers...
