Question

PLEASE DON'T LEAVE UNHELPFUL ANSWERS

1. In what ways does one biotic factor interact with the abiotic factors?

2. Pick one biotic factor, if you were to change it dramatically somehow, how will this change affect the ecosystem?






3. Pick one abiotic factor, if you change it dramatically somehow, how will this change affect the aquarium?

Answer 1

1. One common interaction between biotic and abiotic components of an ecosystem is photosynthesis. Sunlight is abiotic (solely energy), and it fuels the synthesis of sugars and proteins inside plant cells once it is taken up by plant leaves. This process also produces oxygen.



2. Biotic factor that can affect the size of a population in a specific ecosystem:
Number and kinds of predators in the ecosystem.

Predator-prey relationships
When the moose population is high on Isle Royale, the wolves have more food source from preying on the moose. This supports an increase in the wolf population.

3. Temperature
You can change the temperature to freezing it will affect the aquarium because the organisms will not be able to tolerate the new environment if they are species that thrive in warm temperatures.
