Ecosystem distribution is related to precipitation; regions that receive large amounts of precipitation are wet and therefore have increased vegetation.
Explanation:
Precipitation in the form of rain and climate determines the vegetation of an ecosystem. Ecosystems with abundant rainfall will have dense vegetation and one with scarce rainfall will have limited or no vegetation.
Tropical rainforest ecosystems receive large amounts of rainfall distributed year round and have thick vegetation.
Water is the prime growth factor for plants and rainfall is the main source of water for plants. Any ecosystem, maybe a desert, grassland, fertile plain, bushlands, evergreen forest etc depend upon rainfall.
The rainfall determines the density of vegetation, the type of vegetation, greenness, structure of plants or trees like foliage, height, branching etc
Answer:
7
Explanation:
Mechanical advantage is given by the ratio of the distance of the fulcrum from the two objects of the system.
Here the boulder is from the fulcrum and the mass at the other end of the lever is from the fulcrum.
So, mechanical advantage is given by
So, mechanical advantage of the board is 7.
This could help the elephant population rebuild by taking away some of its (predators). Elephants are a keystone species because they dig watering holes, which all animals need. You increase the number of elephants, you increase water availability.
They no probably no longer eat the same things, or one of the populations has adapted to its environment and the other flies continue to be normal.
