Answer:
1: water availability and habitat space
Step-by-step explanation:
Abiotic factors are non-living factors that affect an ecosystem. Some examples of abiotic factors include:
- Temperature
- Rainfall
- Sunlight
- Soil type
- Altitude
The carrying capacity of an ecosystem is the maximum number of organisms that can live in a particular area. The carrying capacity is determined by the availability of abiotic resources, such as water and habitat space.
If there is not enough water or habitat space, the carrying capacity will be lower. This is because the organisms will not be able to find the resources they need to survive and reproduce.
The number of mates and predators are biotic factors, not abiotic factors. Biotic factors are living factors that affect an ecosystem. Some examples of biotic factors include:
- Competition
- Disease
- Predation
The number of mates and predators can affect the carrying capacity of an ecosystem, but they are not the only factors. The availability of abiotic resources is also important.
