Section 2: Conduct internet research on your selected ecosystem to help you generate a list of three criteria and two constraints. Your criteria and constraints should consider relevant factors to the problem, such as costs, reliability, safety (to humans and wildlife), human needs, environmental impact, local biodiversity, and the aesthetics of the area. List the criteria in order of most to least important and assign each to a related sub-problem. In the rationale column, explain why you placed your criteria in the order you selected.

Constraints:

Funding

Protective equipment

Research

Installation

Criteria

Fertilizers

Rationale:

This is a big deal being that fertilizers are needed to help plants experts are still looking for ways to knock down the amount used.

Which Sub-Problems does this criteria address?

The main environmental problem associated with fertilizer use is contamination of water with nitrates and phosphates. The nitrogen from fertilizers and manures are eventually converted by bacteria in the soil to nitrates. ... High nitrate levels in drinking water are considered to be dangerous to human health.

Criteria:

Human Waste

Rationale:

Human waste is a large problem and the government is trying to stop the public from disposing of it.

Which Sub-Problems does this criteria address?:

Globally, almost 80 percent of the world's wastewater flows back into the ecosystem without proper treatment. This means that almost a quarter of people drink water contaminated with human waste, according to United Nations Water. That incubates deadly diseases, including cholera, dysentery, typhoid and polio.

Criteria:

Oil  

Rationale:

Oil is needed for just about everything but it is very costly when it comes to the environment.

Which Sub-Problems does this criteria address?

Oil spills have a devastating effect on the environment, ruining habitats and killing the organisms that live there by sticking to them, destroying their food sources and poisoning them. Additionally, oil hurts the economy by harming the fishing industry, as well as other trades that rely on the ocean.

Explanation:

answer: grassland biomes are closer to the equator and receive more rain.

grasslands are biomes that are dominated by grasses rather shrubs and trees. savanna are biomes that exhibit grasses, shrubs and small tree as vegetation. grasslands are located near the equator of the earth. these are found in north america. savanna biomes are found in africa, south america, australia and india. grassland exhibit moderate climatic conditions, it receives   amount of rainfall higher than savanna.   therefore, savanna exhibit dry and hot climatic conditions.

the wetland preservation movement began in the u.s. in earnest with the clean water act (cwa) of 1972. although not specifically written to protect wetlands, the cwa is comprised of a series of regulations designed to prevent pollutants from contaminating u.s. waters.
