Final answer:
Competition, predation, and limited space are factors that can cause a decrease in population growth.
The correct answer is option B) Predation/Competition and D) Space.
Step-by-step explanation:
Factors that can cause a decrease in population growth include:
- Competition: When resources such as food and water are limited, organisms will compete with each other for these resources. This competition can lower birth rates and increase death rates, ultimately decreasing population growth.
- Predation: Predators can reduce the population size by hunting and killing individuals. This can limit population growth as it decreases the number of individuals able to reproduce.
- Space: When the available space for a population becomes limited, it can restrict the population's ability to grow. Lack of space can lead to increased competition and reduced reproductive rates.
The correct answer is option B) Predation/Competition and D) Space.
