Answer 1

Ans 1: Producer- synthesize their own food are called producer e.g. autotrophs.

Consumer- can't synthesize their own food, depend on autotrophs e.g. heterotrophs.

Ans 2: Lipid- long aliphatic chain and their derivatives are called lipid.

Phospholipid- lipid contain phosphate group called phospholipid

Ans 3: starch

Ans 4: these are the essential requirement to live the life. foods provide energy, water helps in metabolic process, air required for respiration.

Ans 5: protein

Ans 6: beacuse decomposers are also depend on other for their food.
