LekaFEV [45]3 years ago
8 0

The correct answer is option A

Soil reaction can be defined as the measure of acidity or alkalinity of soil. The pH of the soil or the reaction of the soil is an measurement or indication of the alkalinity or acidity of the soil. This defines the nature of the soil, whether the soil is acidic or basic in nature. If the amount of hydrogen ions is more then the soil is acidic and if the amount of hydrogen ions are less then the soil is basic.

Algae are not plants, animals or fungi. They belong to Kingdom Protista, a diverse group of single-celled eukaryotes.
Protists have their own kingdom because many species share some characteristics of plants, animals or fungi.
Algae belong to the group of plant-like protists.
They are autotrophs that fulfill the role of producer in ecosystems because they make their own food via photosynthesis, like plants.

-BARSIC- [3]

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.
