Why do plants and animals depend on each other?
Answer:
Answer by Student
-
Plants and animals depend on each other because they are part of the
biosphere
, which is the living component of the environment.
-
They have various
interactions
and
relationships
that benefit both of them.
-
Some of the reasons why plants and animals depend on each other are:
-
Plants provide
food
and
oxygen
for animals. Plants make their own food by using sunlight, water and carbon dioxide through a process called photosynthesis. They release oxygen as a by-product of this process. Animals use this oxygen for breathing and releasing energy. They also eat plants or other animals that eat plants for getting nutrients.
-
Animals provide
carbon dioxide
and
fertilizers
for plants. Animals breathe out carbon dioxide as a waste product of respiration. Plants use this carbon dioxide for making food through photosynthesis. Animals also produce waste materials like urine and feces that contain nitrogen and other minerals. These waste materials act as natural fertilizers for plants and enrich the soil.
- Plants and animals help in pollination and seed dispersal for each other. Pollination is the transfer of pollen grains from the male part to the female part of a flower. This helps in fertilization and reproduction of plants. This helps in germination and growth of new plants. Some animals like bees, butterflies, birds, etc. help in pollination by carrying pollen grains from one flower to another. Some animals like squirrels, monkeys, birds, etc. help in seed dispersal by eating fruits and dropping seeds in different places.
