a) Explain why insectivorous plants such as Drosera species trap and digest insects. (1 mark)

b) Discuss the relationship between plant nutrition and animal nutrition. (2 marks)



Answer :

Final answer:

Insectivorous plants attract and digest insects to supplement their nutrients. They have evolved specialized leaves to capture insects due to low soil nutrients.


Explanation:

Insectivorous plants, such as Drosera species, trap and digest insects to supplement their nutrient intake. These plants have evolved specialized leaves that attract and capture insects due to low nutrient availability in their habitats. For example, the Drosera species grow in nitrogen-deficient bogs and use gland-secreted mucilage to trap insects for nutrients. Insectivorous plants like the Venus flytrap obtain minerals from prey to compensate for soil deficiencies and attract insects through nectar secretions.
