Answer 2

1 Plants make food in their leaves. The leaves contain a pigment called chlorophyll, which colors the leaves green. Chlorophyll can make food the plant can use from carbon dioxide, water, nutrients, and energy from sunlight. This process is called photosynthesis.

2 Nutrition is the mode of taking food by an organism and its utilisation by the body. The mode of nutrition in which organisms make food themselves from simple substances is called autotrophic (auto = self; trophos = nourishment) nutrition. Therefore, plants are called autotrophs.

3 The process of breaking down of complex component of food into simpler substances is called digestion.

4 The hypothalamus has emerged as the major site of food intake (Hussain and Bloom, 2013). The hypothalamus receives signals for the gut, pancreas, liver, and adipose tissueas well as other parts of the brain

5 Digested nutrients pass into the blood vessels in the wall of the intestine through a process of diffusion. The inner wall, or mucosa, of the small intestine is lined with simple columnar epithelial tissue.

6 faecal matter is removed from our body by the process of egestion.note that there's a difference between excretion and egestion.excretion is the process of removing toxic materials through urine.
