LIFE SCIENCE

Detailed explanation-1: -Organisms and their nonliving environment are connected. Natural catastrophes can upset the balance of an ecosystem. Recycling of garbage, solid wastes and certain crops for generating energy has been accomplished already. All the resources of solid waste shown in the pie graph are biodegradable.

Detailed explanation-2: -If a population exceeds carrying capacity, the ecosystem may become unsuitable for the species to survive. If the population exceeds the carrying capacity for a long period of time, resources may be completely depleted. Populations may die off if all of the resources are exhausted.

Detailed explanation-3: -Ecology is the study of the relationships between living organisms, including humans, and their physical environment; it seeks to understand the vital connections between plants and animals and the world around them.
