You look into your jar ecosystem and observe that the mealworm you placed inside has unfortunately died. Is the dead mealworm a biotic or abiotic factor in your jar ecosystem?

• biotic

• abiotic

• was once BIOTIC, but is now ABIOTIC

• A dead mealworm is no longer a part of the ecosystem.

Answer explanation

The dead mealworm is considered a biotic factor because it was once a living organism. remember that only NONLIVING things (meaning it was never ever alive) are considered abiotic factors.

A student writes in his notebook while examining Peva, Ms. Kim’s service dog, “Peva (the dog) often moves her legs and sleeps with her eyes slightly open.” What type of observation is he making in this statement?

• Quantitative Observation

Which process describes the movement of water OUT from the plant’s leaves into the atmosphere?

• Infiltration

• Evaporation

• Transpiration

• Runoff

Answer explanation

Transpiration is the process where water vapor is released from plant leaves into the atmosphere, primarily through small openings called stomata. This distinguishes it from evaporation, which involves water changing from liquid to vapor. (Also remember that photosynthesis produces water, so there must be a way for it to go out of the plant!)
