Answer:

Because there is already presence of soil and nutrients in secondary succession

Explanation:

Ecological succession, which is the series of gradual change that occurs in a community over time, can be of two forms namely: primary succession and secondary succession.

- Primary succession is a kind of succession that occurs in a barren land where no form of life has existed before while secondary succession occurs on a land that has been previously colonized by certain organisms called PIONEER SPECIES, and hence, a substrate containing nutrients called SOIL for growth is available during secondary succession.

This accounts for the reason the secondary succession is faster than the primary succession because there is already presence of soil and nutrients in secondary succession.

Imagine a bodybuilder flexing their muscles. which type(s) of tissue go into that action?
mojhsa [17]

Answer:

The tissues that come into action are cartilaginous, bone, muscular and tendon.

LuckyWell [14K]

Answer:

Nitrogen fixation occur when nitrogenase convert N2 into ammonia gas that living thing can take up.

Ammonification bacteria in soil or fungi will convert nitrogen into ammonia compound.

3. Nitrification.

Soil bacteria converts ammonia to nitrite.

Soil bacteria then convert nitrite ions into nitrate.

4. Denitrification in this process , nitrate is converted to nitrogen gas, which are then released to the atmosphere

Assimilation occurs when minerals and vitamins are absorbed in the food by the intestine.

Explanation:

Nitrogen fixation is the process where nitrogen is fixed and made available by living things in which nitrogenase convert nitrogen to ammonia.

Ammonification is the process by which organic nitrogen is converted to ammonia compounds by bacteria and fungi

Nitrification is the process where nitrifying bacteria convert ammonia to nitrite and then nitrite to nitrate.

Denitrification is the process where nitrate is reduced or converted to nitrogen gas.

Assimilation is the process of absorbing vitamins and minerals from food by the intestine.
