6 Questions
Which term refers to nonliving factors in an ecosystem?
Abiotic factors
When one species affects another species in competition for the same resources, it is an example of:
Competition
What kind of factors affect the number and types of organisms an ecosystem can support?
Environmental factors
Describe the evidence of predatory, mutually beneficial, and competitive populations within an ecosystem and across ecosystems.
Predatory populations can be evidenced by data of population changes, observations, or reading material on interactions like deer and wolf populations. Mutual beneficial populations, like bees and flowers, can be observed in ecosystems. Competitive populations, such as birds in an area, can also be identified and described.
How do living (biotic) and nonliving (abiotic) factors affect the number and types of organisms an ecosystem can support?
Living factors like competition for resources and predation, as well as nonliving factors like temperature and water availability, can limit the number and types of organisms an ecosystem can support.
Explain how one species affects another species in competition for the same resources in an ecosystem.
One species affects another in competition by vying for the same resources, which can lead to changes in population sizes, behaviors, or adaptations to reduce competition and survive.
Study Notes
Non-Living Factors in Ecosystems
- Abiotic factors refer to non-living components of an ecosystem, such as light, temperature, water, and nutrients.
Competition in Ecosystems
- Intraspecific competition occurs when individuals of the same species compete for resources.
- Interspecific competition occurs when individuals of different species compete for resources.
Factors Affecting Ecosystems
- Biotic factors, including living organisms, affect the number and types of organisms an ecosystem can support.
- Abiotic factors, including non-living components, affect the number and types of organisms an ecosystem can support.
Interactions in Ecosystems
- Predation: one species captures and consumes another species.
- Mutualism: two species benefit from each other's presence.
- Competition: one species affects another species by competing for resources.
Species Interactions and Resource Competition
- When one species affects another species in competition for the same resources, it is an example of interspecific competition.
- Competition for resources can affect the number and types of organisms an ecosystem can support.
Test your knowledge on identifying living and nonliving factors, understanding required resources for organisms, and recognizing the effects of species interactions in an ecosystem. Also, learn to describe evidence of predation and competition.
