Abiotic and Biotic Factors Assessment
Name _________________
List four 4 abiotic factors that limit organisms in an ecosystem.
Water
Sun , Temperature
25._________________________________________
26. ______________________________________
Changing conditions
Soil – Nutrients
27. ________________________________________
28. ______________________________________
Drought, flood, volcanoes
29. What happens to abiotic factors when biotic populations increase?
When biotic populations increase, abiotic factors tend to be decreased due to a greater
________________________________________________________________________________________
demand for the resources like grass, water, shelter, food sources.
________________________________________________________________________________________
________________________________________________________________________________________
30. Explain how organisms compete for abiotic factors in an ecosystem.
Organisms compete for abiotic factors by growing taller to get more sunlight. Adapt to living
________________________________________________________________________________________
with less water, like the cacti, adapt to living in nutrient poor soils fewer but more hardy plants.
________________________________________________________________________________________
Temperature – organisms either migrate away from or to different climates.

31. List two biotic factors that compete for biotic factors in a forest ecosystem.
Wolf and bear (look for carnivores) hunt for the same prey.

Students may have many different answers here.

32.List two biotic factors which could survive in a desert ecosystem and explain which
abiotic factors they would depend on and why.
Again students will have many different ideas - look for
_______________________________________________________________________________________
organisms that are desert hardy and their explanations
_______________________________________________________________________________________
should include abiotic factors like heat, lack of water,
_______________________________________________________________________________________
Plants that can survive in nutrient poor soils, extreme temps
_______________________________________________________________________________________
.
Hot in the day and cold at night. flash floods etc.
