Question

1. competition for resources is a limiting factor because * 0/6

abiotic factors such as light, water, and temperature are present
cities, highways, campgrounds and orchards provide alternate environments for animals and plants
there is only a limited amount of food and living space available in any ecosystem
predator - prey populations often increase and decrease in cycles

1. what type of organism is primarily responsible for driving * dropdown 0/6
2. animals
3. plants
4. fungi
5. bacteria

Explanation:

• For question 14: Limiting factors restrict population growth. In an ecosystem, food and living space are resources. If there's only a limited amount (as stated in option 3), competition for them occurs, making it a limiting factor. Option 1 just lists abiotic factors but doesn't explain competition as a limiting factor. Option 2 is about alternate environments, not competition as a limiting factor. Option 4 is about predator - prey cycles, not resource competition as a limiting factor.
• For question 9: Bacteria play crucial roles in the nitrogen cycle. They are involved in processes like nitrogen fixation (converting atmospheric nitrogen to a usable form for plants), nitrification (converting ammonia to nitrates), and denitrification (converting nitrates back to nitrogen gas). Animals, plants, and fungi do not have the same central and diverse roles in driving the nitrogen cycle as bacteria.

Answer:

1. C. There is only a limited amount of food and living space available in any ecosystem
2. 4. Bacteria
