and Abiotic
Content:

Importance
Ecology
understanding ecological
relationships
understanding biotic and abiotic
factors such as pests, soil
nutrients, and water availability
can help optimize crop yields
biotic factors like the role of plants
in soil formation can be studied as
well as abiotic factors such as
weathering, erosion, and rock
formation

Directions: Select and perform only one of your
choice and by following the given criteria below.
1.Construct a caricature of your desired
environment where biotic and abiotic factors thrive.
2.Create a 3D book of the ecosystem. Surf the
internet for sample 3D books.
3.Make a cartooning on how human beings destroy
the environment. Provide 2 paragraph of the
solutions you can cite on how to lessen or eradicate
the effects of the destruction.
4.Make a comic strip on your exploration of the
environment where biotic and abiotic factors thrive.
