Why is variety in crop plants important for food security?

Biology
1 answer:
aev [14]2 years ago

Answer:

Disease and Famine

Explanation:

If there is a disease that affects a type of plant, having other types of crops to rely on could save one from starvation. Also, only planting one crop in an area can change the pH and nitrogen levels in negative ways, so that eventually no plants can grow there. Not to mention the obvious balanced diet needed for a healthy body.

How does dispersal help different species? dispersal helps different species to increase their range of places, thereby helping
icang [17]

Dispersal helps different species to increase their range of places, thereby helping to increase their population size in different regions. Dispersal also helps to avoid crowding of diseases of a single location as species move to different locations.

<h3>What is dispersal?</h3>
  • Dispersal is the act of distributing things over a large area. It is when the individuals or seeds move from one site to their growing site.
  • Dispersal can be active (move by oneself) or passive (require dispersers).
  • Seed dispersal is the mechanism of transport of plant seeds to new sites for germination and the establishment of new individuals and colonies.
  • This depends upon the effectiveness of the seed dispersers.
  • Seed dispersal occurs by wind, water, animals, bats, explosions or gravity of the earth.
  • Dispersal of seeds is very important for the survival of plant species.
  • If the plants of same type grow too closely, they have to compete with each other for light, water and nutrients from the soil.
  • Seed dispersal allows plants to spread out from a wide area and avoid competing with one another for the same resources.
