<u>Answer 1</u>- Earthworms are decomposers. They decompose the organic matter and convert the complex substances into simpler digested molecules. These molecules are released into the soil by the feces of earthworms. This way earthworms replenish the soil fertility and return the nutrients back to the ecosystem.

<u>Answer 2</u>- Food chain is a series in which organisms are placed in a systematic order of flow of energy and nutrients. An example of food chain with earthworm is shown in image shared below.

Romashka [77]

Answer:

nucleic acids.

Explanation:

The fusion of the sperm with the egg results in the formation of a zygote that develops into a new offspring. Twins refers to the two offspring which are a result of the same pregnancy. They are of two types. Monozygotic twins are a result of the single zygote (formed by the fusion of one egg with a single sperm) spiltting into two embryos forming the identical twins. Dizygotic twins are a result of two eggs fertilized with two different sperms forming the fraternal twins.

Identical twins are genetically simliar. The genetic material is derived from the same embryo and thus, the DNA of the identical twins are nearly identical. The spilitting of the embryo formed results in the separation of the same genetic material or identical DNA getting incorporated into the twins making them look alike in majority of the cases.

What property of water is partly responsible for creep
photoshop1234 [79]

The property of creep can be defined as the tendency of a solid material to move or deform slowly under the influence of mechanical stresses. This can occur as a result of long-term exposure to high levels of stress which is below the yield strength of the material.

The water's ability to freeze and thaw is the basic property of water that is partly responsible for creep.
