As the primary consumers are more in number than the primary producers in the English Channel ecosystem, therefore they cannot have a high turnover rate. The turnover rate of the apex consumers does not affect the number of primary producers.
Do primary producers have a high turnover rate?
d. The primary producers have a high turnover rate.
What are primary producers and why are they so important to an ecosystem?
Primary producers are the foundation of an ecosystem. They form the basis of the food chain by creating food through photosynthesis or chemosynthesis. … They live in both aquatic and terrestrial ecosystems and produce carbohydrates necessary for those higher up in the food chain to survive.
What would happen to the food web if all of the species of row B were wiped out by a natural disaster such as an oil spill Why?
What would happen to the food web if all of the species of the entire row B was wiped out by a natural disaster such as an oil spill? … The tertiary consumers would die out due to lack of food and this could potentially lead to collapse of the entire food web.
What is a primary producer in an ecosystem?
organisms, such as plants and phytoplankton, that can produce their own food through photosynthesis or chemosynthesis; also called autotrophs.
What is the difference between primary and secondary production?
Primary production: this involves acquiring raw materials. … Secondary production: this is the manufacturing and assembly process. It involves converting raw materials into components, for example, making plastics from oil.
Who are called primary producers?
Plants are called primary producers because plants produce their food themselves through the process of photosynthesis.
Why are producers more important than consumers?
Explanation: Without decomposers, life cannot exist. Producers produce oxygen and food (to consumers) and they need organic and inorganic materials, water, air, carbon dioxide, etc.
What if all primary producers lose their ability to photosynthesize?
Plants, algae, and photosynthetic bacteria act as producers. … If the plants or other producers of an ecosystem were removed, there would be no way for energy to enter the food web, and the ecological community would collapse.
Why are there so many primary producers?
We eat more than we produce, but the more primary consumers will eat the consumers, as consumers will consume energy from producers. There is more producers, because without producers consumer populations would go down. So this is proving that we have more producers in an ecosystem than consumers.
Why do scientists more commonly Analyze net primary productivity compared with gross primary productivity?
Why do scientists more commonly analyze net primary productivity compared with gross primary productivity? Net primary productivity incorporates features like production at present and next trophic levels, whereas gross primary productivity does not.
What is the reason why net productivity diminishes with each higher trophic level?
Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level. Trophic level transfer efficiency (TLTE) measures the amount of energy that is transferred between trophic levels.
Why is a food web a more realistic model of energy flow than a food chain?
A food web is a more realistic way of portraying an ecosystem than a food chain because food chains imply that organisms only eat one type of organism which is rarely true. Food webs that depict the complexity of feeding relationships in an ecosystem in a more accurate manner.
Are plants primary producers or consumers?
Primary producers—plants, algae, and bacteria—make up the base of the pyramid, the first trophic level. Through a process called photosynthesis, producers capture energy from the sun and use it to create simple organic molecules, which they use for food. Consumers constitute the upper trophic levels.
Why are plants primary producers?
Food produced by photosynthesis forms the base of most ecosystem food chains. … Plants are called primary producers because they produce the material and store the energy at the bottom of the food chain.
