B7 - Ecology

Question 2

What does decomposition produce

Answer 2

Compost

Question 3

What is compost and what is it used for

Answer 3

Compost is decomposed organic matter that is used as a natural fertilizer for crops and plants

Question 4

What is responsible for decomposition

Answer 4

Microwave organisms such as bacteria and fungi , as well as detritus feeders

Question 5

What are the four factors affecting the rate of decay

Answer 5

Temperature water availability oxygen availability and the number of decay organisms

Question 6

How does temperature affect the rate of decay

Answer 6

Warmer temperatures make things.Do decompose quicker because they increase the rate at which the enzymes involved in decomposition worker.If it is too hot, the decomposition stop stops because the enzymes become d natured.And the organism’s die really cold temperatures also slow down the rate of decomposition

Question 7

How does water availability affect the rate of decay

Answer 7

Decay takes place faster in moist environment because the organisms involved in decay need Water to carry out biological processes

Question 8

How does oxygen availability Effect the rate of decay

Answer 8

Many organisms need oxygen to respire which they need to do to Survive microorganisms involved in anaerobic decay dont need oxygen

Question 9

How does the number of decay organisms affect the rate of decay

Answer 9

The more microorganisms and detritus feeders there are the faster decomposition happens
