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 best describes the flow of energy and matter through the terrestrial ecosystem?
Which of the following best describes the flow of energy in most terrestrial and near-surface marine ecosystems? Producers use energy from the sun to make organic matter, such as sugars, from carbon dioxide and water and are then consumed by organisms higher in the food chain.
What is the relationship between matter and energy in an ecosystem ?( 1 point?
Matter flows through ecosystems; energy cycles within ecosystems.
What is the main difference between the flow of energy and nutrients in an ecosystem quizlet?
How does the way that matter flows through an ecosystem differ from the way that energy flows? Energy flows one way, matter is recycled within and between ecosystems. Why do living organisms need nutrients? To build tissues and carry out life functions.
Which of the following ecosystems encompasses all of the others?
A biosphere encompasses all the Earth’s ecosystems. The biotic components of biosphere includes the land, air, and water.
Which statement best describes energy transfer in a food web quizlet?
The correct answer is 3. A food web shows how energy is transferred in an ecosystem. For instance, the solar energy is transferred to the producers such as plants so that they can convert it into chemical energy. The chemical energy stored in producers are transferred to the consumers once they eat the plants.
Which statement best describes the distribution of energy in this food web?
Which of the following correctly describes the distribution of available energy among the different trophic levels of any food web? The amount of available energy is the highest among the primary and tertiary consumers of the food web.
How is 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.
How do matter and energy flow in the ecosystem?
Producers make all the food that is present in an ecosystem or food web. This means that we can trace all the energy and matter in a food web back to the primary producers. … Producers create their own food, consumers use other organisms as a source of food, and decomposers break down dead plants and animals.
How do matter and energy move through an ecosystem?
How Matter Moves Through Ecosystems
- Decomposers release nutrients when they break down dead organisms.
- The nutrients are taken up by plants through their roots.
- The nutrients pass to primary consumers when they eat the plants.
- The nutrients pass to higher level consumers when they eat lower level consumers.
How do the flow of energy and matter differ from one another?
The key difference between energy flow and matter cycling is that energy flow shows the energy transmission from one trophic level to next trophic level in food chains while matter cycling shows the flow or cycling of elements through the living and nonliving parts of ecosystems.
What describes the movement of energy and nutrients in an ecosystem?
The energy and mineral nutrients move from the green plants i.e., producers to the consumers. It is mediated by the foodchain and food web. … At each trophic level, the stored energy is decreased (10% law). Microbes decompose the dead organisms and minerals again returned to soil.
What is the main difference in the way energy vs nutrients moves through an ecosystem?
Chemical nutrients and energy tend to flow in the same direction for most of an ecosystem. The big difference is that the chemical nutrients are ultimately recycled in the ecosystem while the energy is ultimately lost from the ecosystem to the universe at large. Energy in any ecosystem ultimately comes from the Sun.
