I need to classify each item on the worksheet as either biotic (B) or abiotic (A). Biotic factors are living things, while abiotic factors are non-living parts of the environment.
Let me go through each item one by one:
1.
Sun: This is a star and a source of energy, but it is not a living organism. It is
abiotic (A).
2.
Leaves: These are parts of a plant, which is a living organism. They are
biotic (B).
3.
Shrub: A shrub is a type of plant, which is a living organism. It is
biotic (B).
4.
Trunk of the tree: This is part of a tree, which is a living organism. Even though wood is dead tissue, it is part of a living system. It is
biotic (B).
5.
Rat: A rat is an animal, which is a living organism. It is
biotic (B).
6.
Clouds: Clouds are made of water vapor and are not living. They are
abiotic (A).
7.
Rain: Rain is water falling from the sky and is not living. It is
abiotic (A).
8.
Lynx: A lynx is an animal, which is a living organism. It is
biotic (B).
9.
Soil: Soil is made up of minerals, organic matter, air, and water. While it contains living organisms (like bacteria and fungi), soil itself is considered a non-living component of the environment. It is
abiotic (A).
10.
Bush: A bush is a type of plant, which is a living organism. It is
biotic (B).
11.
Rabbit: A rabbit is an animal, which is a living organism. It is
biotic (B).
12.
Stones: Stones are rocks and are non-living. They are
abiotic (A).
Based on this analysis, here is the completed classification:
Answer:
*
A 1. sun
*
B 2. leaves
*
B 3. shrub
*
B 4. trunk of the tree
*
B 5. rat
*
A 6. clouds
*
A 7. rain
*
B 8. lynx
*
A 9. soil
*
B 10. bush
*
B 11. rabbit
*
A 12. stones
Parent Tip: Review the logic above to help your child master the concept of biotic vs abiotic worksheet.
