Detailed explanation-1: -Each organism has particular forms of these structures that assist their survival. In all environments, organisms with similar needs may compete with one another for limited resources, including food, space, water, air and shelter.

Detailed explanation-2: -Big Ideas: All living things have certain traits in common: Cellular organization, the ability to reproduce, growth & development, energy use, homeostasis, response to their environment, and the ability to adapt.

Detailed explanation-3: -The solar energy captured by the leaves is used to make food which is stored in the plant. All organisms are directly or indirectly dependent on plants for their food. Thus, the sun is the ultimate source of energy for all living organisms.

Detailed explanation-4: -When resources are limited, “competition, ” increases and some populations of organisms will decrease. Some individuals may even be weaker or smaller without the resources they need. Natural disasters, environmental changes, and humans can all have an effect on the availability of resources.

Detailed explanation-5: -The common limiting factors in an ecosystem are food, water, habitat, and mate. The availability of these factors will affect the carrying capacity of an environment. As the population increases, food demand increases as well. Since food is a limited resource, organisms will begin competing for it.
