Answer:
The abiotic characteristics of an ecosystem that affects man includes: Land surface, rainfall and relative humidity.
Explanation:
In the ecosystem, man occupies the terrestrial habitat which is affected by the abiotic factors listed above.
Abiotic (non- living) factors determine the type of biotic (living) community that is found in an ecosystem. These factors include Land surface, rainfall and relative humidity, just to mention a few.
--> LAND SURFACE: This is responsible for the marked variation in the vegetation of a place. For example, a mountain in the tropics may have a rain forest vegetation at it's base and an afroalpine vegetation near its peak. The gradient of the slope affects the growth of organisms. A steep slope encourage fast run - off of water and therefore encourages erosion, which results in shallow and infertile soil. This in turn AFFECT man's farming activities as there would be little to no crop yield.
--> RAINFALL: Water is a very important abiotic factor that affects life. The main source of water to terrestrial habitat is rainfall. When rain falls, a greater percentage of it sinks into the soil while the rest run- off into water bodies. Water is absorbed by root hairs into the plant and used for photosynthesis to produce food. The absence of rainfall in the environment of man could lead to drought which AFFECTS man negatively.
--> RELATIVE HUMIDITY: This is a measure of the amount of moisture in the atmosphere. It's usually high in hot wet regions. It affects the rate at which water evaporates from the body surfaces of organisms. Low relative humidity cause more water (sweat) to evaporate from body surfaces giving the human body a cooling effect. But in high relative humidity, the sweat cannot evaporate leaving the body feeling hot and sticky. This AFFECTS man as the body tries to cool off in a harder way by increasing rate of respiration and depth of blood circulation.
The correct answer is:
1 - Blue wildebeest (Connochaetes taurinus)
2 - Blue wildebeests
3 - Blue wildebeests and Black wildebeests
4 - Blue wildebeests, Black wildebeests, crocodiles, acacia trees
5 - Maasai Mara
A hierarchical organization is an organizational structure where every component of the organization is subordinate to some other component.
Answer:
In an ecosystem, everything is connected. All ecosystems have some form of food chain and symbiosis. This means that animals rely on each other for life. If one animal were to die then others would be negatively affected. Overall, this means that when biodiversity is lost it becomes harder for organisms to survive. For example, pandas rely on bamboo to survive. So, when it gets cut down and destroyed the pandas also suffer. Additionally, in ecosystems, a wide variety of organisms helps other living creates have more forms of survival. This shows how important biodiversity is.
Answer:
Y most likely represents springs.
Cell wall - Adds structural support to the cell. Holds the cells together
Cell membrane - Serves as a barrier to the cell and allows more nutrient and molecules to move in and out of the cell without letting things that can harm the cell in.
Outer membrane - Serves the same basic functions a the cell membrane. (Depending on how complicated the class your in is, I would visit this website for more information... https://en.wikipedia.org/wiki/Bacterial_outer_membrane )
Pili - Help the cell move and attach the bacteria to surfaces are other cells.
DNA - Contains the genetic instructions on what the cell can physically do, operate, and reproduce.
Flagellum - Helps the cell move. It kind of acts like a propeller for the cell so that it can move around.
