Answer:

The flow of energy in ecosystems is unidirectional or one-way.

Explanation:

Energy is the ability to do work. Energy flows in one direction in an ecosystem and is not recycled. This is because during the transfer of energy from one level to another, energy is lost. Most of the energy received from the sun by producers, plants, is lost as heat to the surroundings. The rest energy is converted by plants to produce food in the form of chemical energy.

Primary consumers feed on plants and secondary consumers feed on the primary consumers and so on up to quaternary consumers. However, at each level of energy transfer, some energy is lost as heat during respiration, some as unused or undigested materials, while some others are used for each organisms metabolic activities. About 90% of energy in a trophic is used at that trophic level. Therefore, only about 10% as much energy is available to  organisms at each successive trophic level. Therefore, energy is not recycled in ecosystems.

Earth's atmosphere maintains its temperature by means of the earth's energy balance. This refers to how incoming from the sun and outgoing energy from the earth are in balance, thereby keeping earth's temperature constant.

Decomposers, are organisms such as bacteria, fungi, and small animals such as ants and worms that eat and decompose dead and waste organic matter and which recycle nutrients back into food chains making them available for plants use. Therefore, decomposers are an essential components of all ecosystems.

What type of disease transmission is most likely represented by the graph shown below?
yaroslaw [1]

Answer:

A. Person to person.

Explanation:

The graph shows that the disease spreads slowly at first, then rapidly, and slowly at the end. This pattern of transmission is most characteristic of a disease spread from one person to the next. When only one person has the disease, the rate of transmission is slow because that person may only meet a few others. But as the number of people with the disease increases, the number of meetings that spread the disease also increase. At this time, the disease can spread very rapidly. The disease spreads more slowly again when there are only a few people remaining that do not have the disease. With foodborne and airborne diseases, the rate of disease spread is most rapid when the disease first arises and the greatest number of possible victims are available. Graphs of foodborne and airborne transmission show the greatest rate of disease spread at the start of the outbreak.

FYI: This isn't my explanation this is the explanation the question gives! :)

List the two major types of aquatic biomes and state the major factor that differentiates between the two aquatic biomes.
rusak2 [61]

The two major types of aquatic biomes is Freshwater and Marine. The major factor that differentiates between the two aquatic biomes is difference in Habitat.

The two major types of aquatic biomes is Freshwater and Marine.

Freshwater regions include rivers and lakes with comparatively low salt concentration.

Marine regions include Ocean, and Estuaries with comparatively high salt concentration.

The Habitat of the Freshwater and Marine life is the major differentiating factor between them.

The survival of fish is also dependent on the type of Freshwater and Marine environment.

Like, the marine water fishes can survive in a water concentration with high salt concentration.

The working of the organs of the aquatic organisms in Freshwater and Marine determines the concept of osmosis and various life important activities needed for the existence.

Fish in salt water need to maintain stable drinking conditions to maintain healthy life.

Freshwater organism finds easier to get adapted to the water environment. They are less sensitive as compared to marine water.
