Reduced vegetation on Earth results in _____.
Answer:
fragmentation of habitat, soil erosion, soil compaction, and increased input of sediment into waterways.
Explanation:
Reduced vegetation on earth will result in more carbon dioxide in the atmosphere because the plants will not absorb the rest.
The effects of plant removal on soil biota were similar to that in the dry season. For both seasons, understory removal had no significant effects on soil Physico-chemical properties (soil water content, pH, total nitrogen, and soil organic carbon) but the removal of all plants significantly decreased soil pH.
Expansive changes in tundra and boreal vegetation can have significant implications for physical and ecological processes, as well as impacts on communities. Vegetation change that alters land surface darkness influences albedo and surface energy balance.

Body Temperature Control Control of body temperature is important for maintaining homeostasis, particularly in areas where temperature varies widely with time of day and with season.
- An ectotherm is an animal whose regulation of body temperature depends mostly on its relationship to sources of heat outside its body. Most reptiles, invertebrates, fishes, and amphibians are ectothermic.
- An endotherm is an animal whose body temperature is regulated, at least in part, using heat generated by its body. Birds and mammals are endothermic.

How does the right hand rule apply?This relationship is represented by the right-hand rule: the thumb of the right hand indicates the conventional direction of electric current; and the other fingers, by wrapping the conductor through which the current passes, give the direction of the magnetic field lines
By right-hand rule, if the right-hand thumb points in the direction of a current, the magnetic field at a point will be given by the direction of curl of fingers at that point.

Their visual system tends to face both eyes to the front and see in colors, characteristics that improve their sight, as primates rely little on their smell sense and much on their sight.
They are quadrupeds with a svelte body and soft hair. Their tail is long. They move from tree to tree by making use of their extremities. They have a dental comb to clean themselves and others.
They are herbivorous frugivorous.
The three correct answers are,
b. the animal's eyes face forward with overlapping fields of view, providing a three-dimensional view and accurate judging of distance.
c. the animal has long flexible arms and a prehensile tail that help it swing from branch to branch.
d. the animal has five flexible fingers and toes, and an opposable thumb and big toe, all used for grasping tree branches and food items, such as fruits, leaves, and seeds.
