What might happen if one species is removed from a habitat?

Extinctions and Disruptions

If one species in the food web ceases to exist, one or more members in the rest of the chain could cease to exist too. A plant or animal doesn't even have to become extinct to affect one of its predators. The harelip sucker fish, for example, used to eat snails in the 19th century.

What happens when an animal is removed from the food chain?

They would starve and die unless they could move to another habitat. All the other animals in the food web would die too, because their food supplies would have gone. The populations of the consumers would fall as the population of the producer fell.

What was the first animal on earth?

A comb jelly. The evolutionary history of the comb jelly has revealed surprising clues about Earth's first animal.

What would happen if animals went extinct?

If animals went extinct there would be less Carbon Dioxide to support photosynthesis and more complex plants would have a difficult time adapting to the reduced levels of Carbon Dioxide. Plants that survived the extinction of animals would be much simpler than presently complex plants.
