Animals, such as insects, have in turn coevolved with
flowering plants into developing special traits, which enable them
to obtain
a) food
b) shelter
c) a water source
d) nesting sites
Correct ans is a. and b
Basically, animals such as insects and flowering plants shows mutualistic relationship between the two. That means, both which belong to different species work together for the benefit for other. Insects lke honey bees help plants by producing nectar (sugary, sticky substance) which helps in pollination and plants can thereby reproduce. More the attraction of plants towars the insects, more the nectar and better chances of reproduction. Inturn plants also helps insects. The relation between the two evolved over a period of time and it is termed as coevolution.
Flowers communicate with the pollinators i.e the animal that moves the pollen grains from male flower (anther part) to the female flower (stigma) via the strong scent produced by the nectar. With this smell, the insects gets to know how far the flower is. It proceeds in that direction and when it reaches the land where the flower is, and finally that insect feed the flower. This nectar is sweet and sugary and very rich in energy and carbohydrates.
b. Plants also gives shelter to insects (like acacia trees gives shelter to acacia ants), shelter and protection from sunlight.
