Ecology 1
Ecology #1
1- Define abiotic and biotic components of the environment.
Natural environment includes all the living and non-living components occurring naturally on Earth. The biological components of the ecosystem that is the biotic components interact with the physical entities (abiotic components). The scientific study of the interaction of biotic community with each other and with abiotic components is known as Ecology.
Abiotic Components
The abiotic components are also known as the abiotic factors. The abiotic factors in ecology consist of the non-living and physical factors of the environment.
Biotic Components
Biotic components are the living factors of the ecosystem. A biotic factor is any living component that includes a number of interrelated populations of different species in a common environment.
1- What does the biosphere consist of?
From the broadest bio physiological point of view, the biosphere is the global ecological system integrating all living beings and their relationships, including their interaction with the elements of the lithosphere, hydrosphere, and atmosphere.
2- How do ecologists define an ecosystem?
A system formed by the interaction of a community of organisms with their physical environment.
3- What does the competitive exclusion principle state?
In ecology, the competitive exclusion principle, sometimes referred to as Gause's law of competitive exclusion or just Gause's law, is a proposition that states that two species competing for the same resources cannot coexist if other ecological factors are constant.
5-Assume an ecologist is studying interactions among different species in an ecosystem. What level of organization should the ecologist study? Why?
A community is composed of all organisms of all species in a geographic area. A community consists of all plants, animals, fungi, and single-celled organisms in whatever geographical area is being studied. Communities are comprised of so many different species of
