Detailed explanation-1: -The simplest level of organization for living things is a single organelle, which is composed of aggregates of macromolecules. The highest level of organization for living things is the biosphere; it encompasses all other levels.

Detailed explanation-2: -A single organism is the simplest level of ecosystem organization. The carrying capacity of an ecosystem is the number of individuals in a species it can support over time. If a population grows beyond the ecosystem’s carrying capacity, some individuals will not have enough resources to survive.

Detailed explanation-3: -The simplest level of organization (although first year chemistry students would disagree) is the chemical level of organization. At this level, simple atoms combine to form relatively simple molecules.

Detailed explanation-4: -The simplest level at which life exists is the cell. Life is also organized on nonliving levels (below the cell) and levels above the organism.

Detailed explanation-5: -What are five levels of organization in an environment? Levels of organization in ecology include the population, community, ecosystem, biome, and biosphere.
