Question

Draw the diagram of number pyramid keeping foxes as third consumers. What are the consequences if their number increases?

Answer 1

1. If the number of foxes increases, then the competition for food will be very severe and less amount of food will be available for them.

2. As a result some of the foxes may not get enough food and die due to starvation. 

3. This reduces the population of foxes and very few foxes will be left in the forest. 

4. This s increases the chances of survival of secondary consumers birds, hence their number increases. 

5. This increases the availability of food for foxes. Very soon a balance will be established between the number of secondary consumers and foxes.
