Question

Give reason for the following –
(a) Some plants eat insects.
(b) Soil needs to be replenished.
(c) Mistle toe is regarded as a partial parasite.

Answer 1

Answer:

(a) Most plants absorb nutrients through their roots from nutrient-rich soil. Since carnivorous plants grow in nutrient-poor areas they eat insects to get the nutrients they need.

(b) It is necessary to replenish the nutrients into the soil because all the nutrients that soil has are used up by the plants during their growth so for the continuos supply of nutrients to the plants it is necessary to replenish the soil again and again

(c) The mistletoe is dependent on a tiny bird called a flowerpecker to disperse its seeds. The flowerpecker feeds on the fruits (drupes) of the mistletoe. ... This makes the mistletoe a partial parasite. This means that it grows on other plants and trees and draws only the raw material from the host.
