Answer:
Autotrophs are organisms that use light energy or energy stored in chemical compounds to make their own food.
1st order heterotrophs are organisms that eat only plants
2nd order heterotrophs are organisms that eat herbivores
3rd order heterotrophs: organisms that eat herbivores and other carnivores
Top group: carnivores
Explanation:
Producers are named as such because they produce their own food either by photosynthesis or chemosynthesis. These organisms are called autotrophs and include plants.
There are various levels of consumers. The first is first order heterotrophs, which feed on the producers. These are herbivores and include, for example, a deer feeding on grass.
The next is second order heterotrophs, which feed on the first order heterotrophs. E.g. an owl eating a mouse. These are carnivores
The next layer are also carnivores, third order heterotrophs which eat second order heterotrophs, for example a lion eating a zebra.
