Answer:
C. Only 1, 3 and 4
Explanation:
Deforestation is the process of cutting down trees by man, which eventually lead to the the sparseness of trees in otherwise forested areas. The reasons for cutting trees by man may include: habitation by man, clearing the land for agriculture or grazing, or using the timber for fuel, construction or manufacturing as well as mining of minerals.
Deforestation leads to many adverse effects on both man and his environment. These adverse effects include:
Loss of biodiversity in the forests which may lead to extinction of species.; when forest areas are cleared, plants and animals who live in these forests lose their homes and some may eventually die off due to inability to survive in other habitats
Increase in temperature of the earth: Trees serves to cool the earth by removing some gases which cause heating of the earth from the earth. Such gases include carbon dioxide. When these tree are removed, these gases accumulate in the atmosphere leading to increase in earth's temperature.
Also, since tree absorb some gases while releasing others into the atmosphere, when these trees are cut, there would be an imbalance of these atmospheric gases.
This is a symbiotic relationship, where both the partners, fungi, and plants are mutually benefitted by exchange of nutrients and none of them is being harmed by other's presence. It is a mutual cooperation and helps both organisms in survival and nutrition.
Answer:
tundra, taiga, temperate grassland, rainforest
Explanation:
Tundra is known to be the coldest of all the biomes due to the high latitudes in which these areas are found. In this biome, the growth of the trees is limited by the low temperatures and the growing season is restricted to the summer season. The taiga is a type of biome composed of forest found in the subarctic areas, it is for that reason that taiga regions are also called boreal forests. Temperate grasslands are areas where grasses are dominant with very variable temperatures depending on the season (i.e. summer to winter seasons). In this biome, trees are relatively uncommon. Finally, the rainforest is the most diverse tree-rich biome where the high temperature and humidity conditions are optimal for life.
