$\huge \red {\mathbb {ANSWER}}$

1.The flow of energy in the ecosystem is said to be unidirectional because the energy lost as heat from the living organisms of a food chain cannot be reused by plants in photosynthesis.

2.Pesticides are non-biodegradable wastes which pass along the food chain from crops to man or other animals and birds and harm them.
