Plants are producers because they produce their own food through photosynthesis. These balances involve food, water, oxygen, nitrogen, and carbon. Write the names of organisms from a food web diagram on note cards. The population of species in a food chain is shown using a pyramid of numbers. A living thing (almost always a plant) that takes energy from the sun and make its own food. Well, animals don't either. Mountain Ecosystem (Non-Fiction) Read about the many different habitats found within a mountain ecosystem. An apex predator is an animal that feeds on other animals but is at the top of the food web, meaning that it has no predators. Herbivores hello rabbit!!! Scientists put together groups of food chains to make a food web, which shows how all the living things in the river ecosystem rely on each other.
