It is important to know the division or phylum of the various plant species growing in your backyard so as to determine whether they will spread and ruin other crops and plants of yours. Not every plant is beneficial, so you need to know which ones to keep, and which to deplant.
common descent means the evolutionary in biology and how they have something linked with their common ancestors.
Answer:
In grassland ecosystem, first trophic level is the producer. Producers are the organisms which makes their own food, here the producer are grasses. The second trohic level contain herbivores which feed on these grasses. These herbivores are eaten by secondary consumers which belongs to third trophic level and secondary consumers are then eaten by tertiary consumer.
The population of producers are very high so it is placed at the base while tertiary consumer are placed on the top due to low population.

When people speak about convection, they are usually referring to the uneven heating that occurs on the surface of the earth.
Consequences of an inconsistent heating system:
Because of the disparity in temperature distribution, certain areas of the environment are hotter than others, and there are also shifts in volume and tension as a result.
It generates updrafts, which in turn may lead to thunderstorms and other types of severe weather.
The Earth has moved slightly on its axis.
Because the sun's rays are directed directly at the equator, the temperature there is higher than in other parts of the planet.
As you approach farther north or further south of the equator, they drop down in an incline or at an angle.
Because of this, the temperature of the earth is uneven, which in turn shapes the wind and the flow of the sea and makes it possible for life to exist.
