Question

Define the food chain. What will happen if the organisms of the second and third trophic levels are removed? Explain with example.

Answer 1

Answer:

Hola

Here is your answer mate________☺️

Explanation:

When a organism is removed, the organism who eats or hunt them will decrease some because they lost one of the food source even though they still have other food sources. This new organism will brake the balance of the ecosystem so their food sources will decrease by having too many predators that hunt and eat them.

Answer 2

Answer:

Hey mate ! Check ur answer below.

Explanation:

Food Chain

Food chain, in ecology, the sequence of transfers of matter and energy in the form of food from organism to organism. Food chains intertwine locally into a food web because most organisms consume more than one type of animal or plant.

Example

Consider the food chain :

Grass → Deer → Lion

If all the lions are removed from the above food chain, the population of deer will increase greatly, as there will be no lion to consume them as food. Then the density of grass will decrease due to overconsumption by a large number of deer.
