Answer:
Forest biome: It gives us medicinal plants, woods for commercial purpose. Forests provides us rubber and fibers that is very important for the industries for making various products. They also contribute to perform ecological functions such as carbon storage, nutrient cycling, water and air purification. It also provides habitat to the wildlife.
Freshwater biome: We use fresh water for drinking water, irrigation, sanitation systems, and in industrial factories. Water used from groundwater, rivers and lakes is regained by rain and snowfall.
Marine biome: It serves huge amount of oxygen into the environment and absorbs the atmospheric carbon dioxide.
As a result of the activity of human there is a significant decrease in the number of trees. The products now used are synthetically made which were made up of natural fibers previously. The water source such as rivers, lakes, and ponds are polluted due to which many water borne diseases are increasing day by day. The accumulation of waste which are found in marine biome are reducing the number of flora present inside marine ecosystem.
Answer:
An enzyme that aids in digestion.
Explanation: Digestion begins in the mouth and continues throughout the GI track. Amylase is found in salIva and begins to break down maltose and dextrin in the mouth. You can also tell amylase is an enzyme because the suffix “-ase” refers to enzymes.
Answer: Option E
Maintaining very long telomeres promotes cancer cell formation.
Explanation:
Telomere refers to either of the sequences of DNA at each end of a eukaryotic chromosome.
Usually, in eukaryote chromosome replication, telomeres are not replicated.
Hence, they are usually lost resulting in the shortening of the telomere ends after repeated cycle of cell division. This also leads to cell aging and stoppage of cell division.
The shortening of telomere combined with stoppage of cell division, and cell aging initiation prevent CANCER, which thrives on lengthy telomeres

The Yellowstone River ecosystem can support 2,300 bald eagles. This is an example of<u> temperate- zone ecosystems</u>
Explanation:
Yellowstone National Park is a natural paradise with over 70 species of birds,which include trumpeter swans, sandhill cranes, loons, peregrine falcons, osprey and bald eagles
The Greater Yellowstone Ecosystem, with Yellowstone at its core, is one of the largest nearly intact temperate- zone ecosystems on Earth. It has an area of 12–22 million acres; 18,750– 34,375 square miles
<u>Temperate ecosystems are the ecosystem that are characterized by the seasonality in temperature, with cooler winters and warmer summers, and also show various seasonality in precipitation patterns, resulting from seasonal changes in the orientation of Earth's axis relative to the sun.</u>
