GENERAL KNOWLEDGE

Detailed explanation-1: -External factors like climate, parent material, control the ecosystem but not control by ecosystem.-On the other hand internal factors are controlled like decomposition, root competition, shading, disturbance, succession, and the types of species present.

Detailed explanation-2: -They include factors such as light, radiation, temperature, water, chemicals, gases, wind and soil. In some environments, such as marine environments, pressure and sound can be important abiotic components. Amazon River abiotic The Amazon River provides and removes excess water to and from the environment.

Detailed explanation-3: -External factors such as climate, parent material which forms the soil and topography, control the overall structure of an ecosystem but are not themselves influenced by the ecosystem. Internal factors such as decomposition, root competition, or shading.

Detailed explanation-4: -Internal factors are processes that exist within the ecosystem, such as decomposition, succession, and the types of species present. While in equilibrium, an ecosystem can recover from small changes through negative feedback, returning to its original state.
