Answer:
a mycorrhiza
Explanation:
Mycorrhizae are mutualistic associations that occur between fungi and the roots of most vascular plants, which are those that have sap-carrying vessels.
Fungi increase the nutrient absorption capacity of plants while providing sugars and amino acids essential for the existence of fungi. That is, both (fungi and plants) are mutually beneficial. This is because fungi nourish plants and they, in turn, during photosynthesis produce carbohydrates that are assimilated by the fungi.
Mycorrhizae absorb nutrients from the soil and transmit them to plants. In this way, plants absorb water and mineral salts more easily and are therefore able to develop better and resist disease as well as climate change.
<span>Heating
of the Earth due to the Sun's rays causes convection currents of air
upwards. The warm air moves upwards, while cool air from nearby regions
fills in the lower areas.
Heating of the Earth can cause warm water currents that flow from hot
areas like near the equator and tropical areas, while cold water
currents flow from the arctic and antarctic regions and the temperate
regions.
Areas closer to water bodies have a moderating effect. In the morning
the cool sea breeze comes over the land and keeps the temperature lower
than it would have been as the Sun rises up. In the evening, the warm
sea breeze comes in over the land, and thus the night temperature is
higher than it would have been when the sun has set.
Mountains cause rain carrying heavy dark clouds to rise up, and pass
over it. As a result of this, the clouds tend to precipitate and shed
the water as rain on the Mountain slopes. These form streams and rivers,
and continue to flow usually throughout the year. </span>
