What are controls in an ecosystem?
Ecosystems may be controlled by abiotic or biotic factors, or interactions among these. Examples of abiotic controls are numerous and varied. Earlier, we learned that primary production may be limited—or controlled—by light, nutrients, and water.
What are the 5 factors of an ecosystem?
FACTORS OF ECOSYSTEM
- Abiotic factors.
- Light affects living things in terms of intensity, quality and duration. …
- Atmospheric Pressure.
- Humidity affects the rate at which water evaporates from the surface of organisms such as in transpiration or sweating. …
What are the two factors of an ecosystem?
The environment includes two types of factors: abiotic and biotic.
- Abiotic factors are the nonliving aspects of the environment. They include factors such as sunlight, soil, temperature, and water.
- Biotic factors are the living aspects of the environment.
What are the 4 main components of an ecosystem?
From structural point of view all ecosystems consist of following four basic components:

What is top-down control in an ecosystem?
In its simplest form, ‘top-down’ control refers to directional regulation within an ecosystem, where species occupying higher trophic levels exert controlling influences on species at the next lower trophic level (Terborgh et al., 1999).
What makes an ecosystem dynamic?
Ecosystems are dynamic in nature; their characteristics can vary over time. Disruptions to any physical or biological component of an ecosystem can lead to shifts in all its populations. … The completeness or integrity of an ecosystem’s biodiversity is often used as a measure of its health.
What are the 3 biotic factors?
Biotic components are mainly of three groups. These are Autotrophs or Producers, Heterotrophs or Consumers, and Detritivores or Decomposers.
What are the types of ecological factors?
The three types of ecological factors are: (1) Climatic factors which include rainfall, atmospheric humidity, wind, atmospheric gases, temperature and light (2) Physiographic factors which include altitude, effect of steepness and sunlight on vegetation and direction of slopes (3) Biotic factors which include …
