Your question: Which accurately describes the role of the sun in ecosystems?

Which accurately describes the role of the Sun in ecosystems? It is the original source of energy for organisms. … The trophic level reflects where an organism is in the sequence of energy transfers in an ecosystem.

Which statement most accurately describes how matter and energy are used in ecosystems quizlet?

Which statement most accurately describes how matter and energy are used in ecosystems? Energy flows through ecosystems; matter cycles within and through ecosystems. The law of conservation of matter states that matter cannot be created, yet matter is sometimes gained or lost to an ecosystem.

Which statement accurately describes one role of producers?

Which statement accurately describes one role of producers? Producers consume dead organic matter and release the nutrients to make them available for other organisms. Producers obtain all the energy they need for growth and reproduction from the gases in the air and nutrients in the soil.

Which statement most accurately describes how matter and energy are used in ecosystem?

They synthesize organic molecules that are used by primary producers. C) They convert organic materials from all trophic levels to inorganic compounds usable by primary producers. D) They secrete enzymes that convert the organic molecules of detritus into CO₂ and H₂O.

What happens to the population of cod when spawning areas for reproduction are lost and then recovered?

what happens to the population of cod when spawning areas for reproduction are lost and then recovered? the population decreases and then increases to return to a stable state.

What is the most important role of photosynthetic organisms in an ecosystem?

Photosynthetic organisms, including plants, algae, and some bacteria, play a key ecological role. They introduce chemical energy and fixed carbon into ecosystems by using light to synthesize sugars.

What is the major role of Detritivores in ecosystems?

The functions of the detritivores include: They break down the dead and decaying matter, thereby, helping in recycling nutrients. Detritivores such as earthworms that live in soil, aerate the soil and help in plant growth. They help in the removal of dead matter and prevent the spread of diseases.

What is a producer in an ecosystem?

Producers are any kind of green plant. Green plants make their food by taking sunlight and using the energy to make sugar. The plant uses this sugar, also called glucose to make many things, such as wood, leaves, roots, and bark. … Deer are herbivores, which means that they only eat plants (Producers).

Which of the following recycled nutrients does not have an atmospheric component?

The cycling of phosphorus in the environment includes a geological (long-term) cycle and a biological (short-term terrestrial and aquatic) cycle. The phosphorus cycle differs from other nutrient cycles, because phosphorus has no major atmospheric component to its cycle. Phosphorus is essential for all life on Earth.

What is the source of energy that supports the growth of most producers quizlet?

Producers that rely on photosynthesis, such as plants and algae, use energy from the sun to produce and store food. Organisms, such as herbivores, eat those producers to obtain the energy they need for their life processes. In turn, other consumers will eat those organisms.

How are matter and energy used in ecosystems?

In ecosystems, matter and energy are transferred from one form to another. … Decomposers break down dead plant and animal matter. Producers (plants) use sunlight and other nutrients to make their own food through photosynthesis. Consumers are the animals that consume, or eat, other living things.

What is the most likely explanation for the unusual growth of these forests in this marginal habitat?

What is the most likely explanation for the unusual growth of these forests in this marginal habitat? Taproot formation is impossible, so trees developed shallow root beds. Two plant species live in the same biome but on different continents.

Which of the following statements best predicts the effect of increased Cottonwood growth?

Which of the following statements best predicts the effect of increased cottonwood growth on the food web? Increased cottonwood growth will provide more resources for cicadas, resulting in an increase in the kestrel population.
