C.Natural Selection would be the answer
The aquifer which will be most effective in purifying polluted ground water is AN AQUIFER COMPOSED MAINLY OF SAND.
An aquifer refers to a zone of permeable rock strata which transmit ground water freely. An aquifer must be permeable and porous. Ground water can be extracted from an aquifer by using a water well.
Answer:
Explanation:
An aquatic ecosystem is an ecosystem in a body of water. Communities of organisms that are dependent on each other and on their environment live in aquatic ecosystems. The two main types of aquatic ecosystems are marine ecosystems and freshwater ecosystems.Freshwater ecosystems are a subset of Earth's aquatic ecosystems. They include lakes, ponds, rivers, streams, springs, bogs, and wetlands. They can be contrasted with marine ecosystems, which have a larger salt content
Reduce!<span> Buy and use less stuff. This is the best way to conserve natural resources. For example, it takes one ton of raw materials from the earth to make one laptop computer! We can also pay special attention to reducing the amount of non-renewable resources we use. For instance, by reducing our use of non-renewable oil and coal to give us energy and electricity, we can make less air pollution. Instead, we can get energy from the sun, the wind and the ocean's tides to heat our homes and light our rooms. These sources of renewable energy don't create pollution and they will never run out! We can also look for different natural resources to use so that we don't use up too much of one kind. For example, we can make tree-free paper out of plants like kenaf, bamboo, and hemp instead of trees! Using tree-free paper is much better for our forests and all the animals that depend on a healthy forest in order to survive.</span>
Option D (E)
<h3>What are Decomposers?</h3>
Decomposers are organisms present at the end of the food chain. These are organisms responsible for acting on the dead and decaying organic matter left out by other organisms and converting them into inorganic matter or simply into nutrient-rich soil.
<h3>Role of Decomposers</h3>
They help in making nutrients available to the primary producers. In a food chain or food web, they are usually present at the last and complete the life cycle. Decomposers in the case of the terrestrial ecosystems are usually microscopic organisms like <u>fungi, bacteria, or invertebrates like earthworms and millipedes</u> which are responsible for decomposing dead and decaying material.
So, in this particular terrestrial ecosystem, the species at the end of the food web (E) is most likely the decomposer as it ends the food web.
