What is a diagram showing the transfer of energy between organisms called
Food chains are sometimes depicted as energy pyramids to show the flow of energy through ecosystems; the width of each step corresponds to the rate of energy flow through each trophic level, with primary producers at the bottom of the pyramid.
What is a representation of a single path of energy flow within an ecosystem
food web. model that depicts numerous interconnected food chains and pathways in which energy and matter flow through an ecosystem. ecological pyramid. food chain. simple model that depicts a single path for which the energy flows through an ecosystem.
Which type of organisms are found at the base of an energy pyramid
All other organisms in the ecosystem are consumers called heterotrophs, which either directly or indirectly depend on the primary producers for food and energy. The base of the pyramid is made up of species called autotrophs, which are the ecosystems primary producers.
What types of organisms are found at the base of the food chain
These organisms are called the producers, and they obtain their energy directly from sunlight and inorganic nutrients. As you are probably aware, the organisms at the base of the food chain are photosynthetic; plants on land and phytoplankton (algae) in the oceans.
What is the sequence of energy flow through a food chain
Sun ——> Producer ——> Herbivore ——> Carnivore ——> Decomposer is the order in which energy flows through an ecosystem.
Which group of organisms is always found at the base of a food chain or food web quizlet
The organisms at the base or bottom of a food chain are known as primary producers or autotrophs. They use energy from nonliving sources to perform either photosynthesis or chemosynthesis in order to produce their own food.
What is an ecological pyramid describe the three types
The three types of ecological pyramids are the pyramid of number, which depicts the number of distinct organisms that exist at various trophic levels, the pyramid of biomass, which informs us of the volume of living tissue or the total mass of organisms within each trophic level, and the pyramid of energy, which depicts the amount of energy that each trophic level of life expends.
What is a gene quizlet
The set of instructions that govern a trait; a chromosomal DNA segment that codes for a particular trait.
How does nutrients move through an ecosystem
Mineral and non-mineral nutrients are absorbed by trees and other plants through their roots, stored in the leaves, flowers, and other parts of the plant, and either transferred to animals when the plants are eaten, or transferred back into the soil.
How do we call the fraction of energy fixed by photosynthesis and that is invested for the construction of tissues
The rate at which solar energy is converted into sugar molecules during photosynthesis is known as gross primary productivity, or GPP. Producers like plants use some of this energy for metabolism/cellular respiration and some for growth, which involves the formation of tissues.
Which of the following kingdoms contains organisms that obtain their food by absorption through filaments called hyphae
The appropriate response is “Fungi,” then.
Which level of an energy pyramid contains the most energy
As you move up the pyramid through the trophic levels to primary, secondary, and tertiary consumers, the amount of energy decreases and the levels get smaller. The bottom and largest level of the pyramid is the producers, which also contains the most energy.
What are the two main processes that ecosystems depend on
Energy transformations and biogeochemical cycling are the two main processes that ecosystem scientists research.
What is recycled and what is lost in an ecosystem
All chemical elements required by living things are recycled in ecosystems, including carbon, nitrogen, hydrogen, oxygen, phosphorus, and sulfur. Water is also recycled. Unlike energy, which is lost and replaced as it moves through ecosystems, elements are not.
What name is given to the functional compartments of a cell quizlet
Organelles are the term used to describe the functional areas of a cell.
Why is the transfer of energy in a food chain usually only about 10 efficient
Because organisms must use the majority of the energy they receive to build themselves and run life-sustaining processes, such as breathing, reproduction, and movement, there is only 10% of the energy that can be transferred to the next level of the food chain.
Which organisms make up the first trophic levels
The first trophic level is composed of producers, also referred to as autotrophs, which produce their own food and do not rely on any other organisms for nutrition.
Why is it appropriate to say that energy flows and nutrients cycle
Since nutrients can be created, destroyed, or even recycled, they do have a clear end cycle, which is why we say that they “flow,” since anything with a beginning and an end has a cycle.
