What is the role of the decomposer in an ecosystem

Decomposers breakdown dead plants and animals they also break down the waste of other organisms
If decomposers weren't an ecosystem the plants would not get essential nutrients and dad matter and waste would pileup

1

What two organisms are mainly known to be decomposers

Bacteria and fungi

2

Name the type of ecological relationship
As insects fly around and feed off of the nectar of flowers they carry pollen from one flower to another helping the plants reproduce

Mutualism

3

Heartworm is an animal that can live in the heart of dogs the warm gets nutrition but the leaves the dog malnourished

24

Define transpiration

Transpiration is the process where plants absorb water to the roots and then give off water vapor through pores in their leaves an example of transpiration is going to plant absorbs water in its roots

25

What is the difference between evaporation and transpiration

If operation occurs in water becomes paper from bodies of water transportation occurs when water leaves a plant as vapor
