The two most important climatic factors for ecosystems are sunlight and water. Sunlight is necessary for plants to grow, and to provide energy to warm the earth’s atmosphere. Light intensity controls plant growth. Light duration affects plant flowering and animal/insect habits.
Which best explains how abiotic factors affect organisms in an ecosystem?
Which best explains how abiotic factors affect organisms in an ecosystem? A. Abiotic factors rely on living organisms to survive in an ecosystem. … Abiotic factors affect the food chain of organisms within the ecosystem.
Which best explains why producers are an important part of an ecosystem?
Q. Which best explains why producers are an important part of an ecosystem? They pass the Sun’s energy on to other organisms.
Which best explains why many kinds of plants and animals can live together in an ecosystem?
Which best explains why many kinds of plants and animals can live together in an ecosystem? The plants and animals are all part of a food chain and depend on each other to live.
Which of the following best describes why decomposers are needed in an ecosystem?
Decomposers play a critical role in the flow of energy through an ecosystem. They break apart dead organisms into simpler inorganic materials, making nutrients available to primary producers.
Is sunlight abiotic or biotic?
Examples of abiotic factors are water, air, soil, sunlight, and minerals. Biotic factors are living or once-living organisms in the ecosystem. These are obtained from the biosphere and are capable of reproduction. Examples of biotic factors are animals, birds, plants, fungi, and other similar organisms.
How abiotic factors affect an ecosystem?
Abiotic factors make up much of the variation seen between different ecosystems. By determining the availability of essential resources such as sunlight, water, oxygen, and minerals, abiotic factors influence which organisms can survive in a given place.
Why is the sun important to both producers and consumers?
Why is the sun important to both consumers and producers? Most producers need sunlight to make food and consumers are dependent on producers to provide the base of the food chain in an ecosystem. Consumers therefore are indirectly dependent on the sun for their energy as well.
Which answer best describes a producer in an ecosystem?
Producers are organisms that create food from inorganic matter. The best examples of producers are plants, lichens and algae, which convert water, sunlight and carbon dioxide into carbohydrates. … They create the matter, or biomass, that sustains the rest of the ecosystem.
Which answer best describes a decomposer?
Decomposers are organisms that break down dead or decaying organisms; they carry out decomposition, a process possible by only certain kingdoms, such as fungi.
What is ecosystem quizlet?
an ecosystem is a community of living organisms (plants, animals, and microbes in conjunction with the nonliving components of their environment things like air, water and mineral soil) interacting as a system. Biome. major biomes includes deserts, forest, grasslands, tandra, and several types of aquatic environments.
Which best explains how a pond ecosystem is similar to a rainforest ecosystem?
Which best explains how a pond ecosystem is similar to a rainforest ecosystem? Both ecosystems contain large amounts of water. Both ecosystems are found in most parts of the world.
How the animals and plants of a healthy ecosystem are organized and interact?
A healthy ecosystem consists of native plant and animal populations interacting in balance with each other and nonliving things (for example, water and rocks). … Decomposers break down dead plants and animals, returning vital nutrients to the soil. Plants take up these nutrients, along with water, through their roots.
Which of the following best explains why decomposers in the soil and water are important to ecosystems?
Explanation: The main role of the decomposer in any ecosystem is to recycle nutrients once organisms die and recycle nutrients in waste. These nutrients are then released into the ecosystem and are available again for use.
Which statement best describes the role of decomposers quizlet?
Which best describes the role of decomposers in an ecosystem? Decomposers get energy by breaking down decaying matter.
Which of the following best describes the role of decomposers in the nitrogen cycle?
The function of decomposers is essential, as they convert dead matter into simple inorganic molecules. That material will be absorbed again by the producers, and recycled in the production of organic matter. In this way the closed cycle of matter resumes, closely linked to the flow of energy.
