Answer;
-Presynaptic neuron
Explanation;
-When a nerve impulse travels from neuron 1 to neuron 2, neuron 1 is known as the presynaptic neuron.
-This is a neuron from the axon terminal of which an electrical impulse is transmitted across a synaptic cleft to the cell body or one or more dendrites of a postsynaptic neuron by the release of a chemical neurotransmitter.
- A postsynaptic neuron is a neuron to the cell body or dendrite of which an electrical impulse is transmitted across a synaptic cleft by the release of a neurotransmitter from the axon terminal of a presynaptic neuron.
Organisms compete for the resources they need to survive- air, water, food, and space. In areas where these are sufficient, organisms live in comfortable co-existence, and in areas where resources are abundant, the ecosystem boasts high species richness.

Answer:
Explanation:
Crop rotation
Rotation of crop is important to help conserve nutrients that are available in the soil and prevent total use up of the nutrients. The same type of plants all year round on the same soil keeps on draining the land of the same nutrients needed for their growth. Rotation of different can help maintain soil nutrients level as some crop fixes nutrients in the soil.
Natural mulching
The use of cover cops as mulch helps protect the soil and allows for retention of nutrients. When cover crops are harvested the leaves can be turned back into soil to release nutrients that are stored up in the plant part.
Composting is the process of decomposing organic matter this could include animal waste such as dung,leaves both green and dead, kitchen. This waste are stored up, little water is added to moist and then allow to decompose it can be mixed together after few days to aerate after. After decomposing to form compost it can be added to the soil. It is usually rich in nutrients.
