What 2 factors determine biodiversity?
Biotic, abiotic and human influences are all factors that affect biodiversity in an ecosystem.
What two 2 factors are used to determine how much biodiversity an ecosystem has?
The two main factors taken into account when measuring diversity are richness and evenness. Richness is a measure of the number of different kinds of organisms present in a particular area. For example, species richness is the number of different species present.
What factors determine ecosystem diversity?
Broadly speaking, the diversity of an ecosystem is dependent on the physical characteristics of the environment, the diversity of species present, and the interactions that the species have with each other and with the environment.
What are the two most important factors in an ecosystem?
Two main components exist in an ecosystem: abiotic and biotic. The abiotic components of any ecosystem are the properties of the environment; the biotic components are the life forms that occupy a given ecosystem.
What two factors influence biodiversity of an island?
Terms in this set (29) The number of species found on an island is determined by a balance between two factors: the immigration rate (of species new to the island) from other inhabited areas and the extinction rate (of species established on the island).
What are the 3 factors that make up biodiversity?
Biodiversity is usually explored at three levels – genetic diversity, species diversity and ecosystem diversity. These three levels work together to create the complexity of life on Earth.
What are the 2 main limiting factors for deciding if an organism can survive in an environment?
Carrying capacity, or the maximum number of individuals that an environment can sustain over time without destroying or degrading the environment, is determined by a few key factors: food availability, water, and space.
What do you know about biodiversity?
Biodiversity is a term used to describe the enormous variety of life on Earth. … Biodiversity refers to every living thing, including plants, bacteria, animals, and humans. Scientists have estimated that there are around 8.7 million species of plants and animals in existence.
What is diversity of ecosystem?
Ecosystem Diversity can be defined as the variety of different habitats, communities and ecological processes. A biological community is defined by the species that occupy a particular area and the interactions between those species.
What are the main factors in ecosystem diversity quizlet?
The four major components of biological diversity are: Functional Diversity (biological or chemical processes such as energy flow and matter recycling needed for the survival of species, communities, and ecosystems), Ecological Diversity (the variety of terrestrial and aquatic ecosystems found in an area or on the …
Which factor influences the biodiversity of an ecosystem the most?
Historically, habitat and land use change have had the biggest impact on biodiversity in all ecosystems, but climate change and pollution are projected to increasingly affect all aspects of biodiversity.
