EVERYDAY SCIENCE

Detailed explanation-1: -humidity in the air forms fog in a valley. Tree roots (biotic) split apart rocks (abiotic) in the ground is an example of how biotic and abiotic factors interact. Therefore, option (C) is correct.

Detailed explanation-2: -A simple example would be of abiotic interaction in plants. Water, sunlight and carbon dioxide are necessary for plants to grow. The biotic interaction is that plants use water, sunlight and carbon dioxide to create their own nourishment through a process called photosynthesis.

Detailed explanation-3: -Ecosystem: An ecosystem consists of all the biotic and abiotic factors that influence that community.

Detailed explanation-4: -An abiotic factor is a non-living part of an ecosystem that shapes its environment. In a terrestrial ecosystem, examples might include temperature, light, and water. In a marine ecosystem, abiotic factors would include salinity and ocean currents.

Detailed explanation-5: -The rainforest is stratified into three distinct vegetation layers based on access to sunlight. It is an excellent example of how biotic factors like plant growth are dependent upon abiotic factors like sunlight. Biotic factors are always dependent upon the abiotic factors that shape their world.
