Answer 2

d. Algae is not a physical factor in the ecosystem.

Algae:

• Algae are a type of plant that is commonly found in water.

• Algae, like all plants, have a pigment called chlorophyll that it uses to convert sunlight into food.
• It cannot be considered a physical factor in the ecosystem.

Explanation for incorrect answer:

a. Sunshine:

Sunlight is the light of the sun or the location where it shines. Sunshine is one of the abiotic variables that vary from one ecosystem.

b. Rain:

Rain is water droplets that fall from the sky. Rain is also considered an abiotic variable in terrestrial ecosystems.

c. Soil

Soil is the loose surface material that covers the majority of the land. It is made up of both inorganic and organic particles.

Hence, Algae does not exist as a physical component of the ecosystem.
