Answer:
Many plant crops need more phosphorus than is dissolved in the soil to grow optimally. In addition, crops are usually harvested and removed – leaving no decaying vegetation to replace phosphorus. Therefore, farmers replenish the phosphorus ‘pool’ by adding fertilisers or effluent to replace the phosphorus taken up by plants.
Explanation:
Secondary succession usually occurs faster than primary succession because the substrate is already present. Compared to the image below, secondary succession does not need to have pioneer species colonize the land nor does decomposition need to occur to create a layer of topsoil.

Bulb serves as a food mass supplying the plant with adequate nutrients that will allow for production of offspring or more onions that can survive.
<h3 /><h3>What is an ecosystem?</h3>
An ecosystem is a community of plants and animals that live together and benefits from each other.
- Survival in an ecosystem is based on the ability of the individual to reproduce their kinds that will survive.
- The bulb in onions act as a store of food for the plants to feed on and grow till maturity where it can also produce more of it's kind.
Without the bulb that stores food the plants cannot grow and therefore the chances of survival is low.
Therefore, the bulb serves as a food mass supplying the plant with adequate nutrients that will allow for production of offspring or more onions that can survive.
