10 Questions
What is the primary function of biogeochemical cycles in an ecosystem?
To govern the circulation of essential elements
In the carbon cycle, what are the primary processes involved in the movement of carbon?
Photosynthesis, respiration, and decomposition
Which of the following is a key role of bacteria in biogeochemical cycles?
Fixing nitrogen for use by organisms
How do human activities impact biogeochemical cycles?
By disrupting natural cycles and causing environmental issues
What does an ecological niche encompass in ecology?
The function and environmental conditions of a species within its habitat
What is the main difference between producers and consumers in an ecosystem?
Producers can generate their own food through photosynthesis, while consumers cannot.
What is the significance of the 10 percent law in the energy flow of an ecosystem?
It states that only about 10% of energy is passed on to the next trophic level, with the rest being lost as heat.
Why is energy flow in an ecosystem considered not 100% efficient?
Because some energy is lost as heat and not all absorbed energy is used.
How does a food web differ from a food chain in an ecosystem?
A food web is more complex and shows how various food chains intersect, while a food chain is a linear sequence.
Why do consumers need to obtain energy by consuming other organisms in an ecosystem?
Consumers cannot generate their own food through photosynthesis like producers.
Test your knowledge on the fascinating process of energy flow in ecosystems, from the sun to different levels of the food chain. Learn about the efficiency of energy transfer and the roles of producers and consumers in an ecosystem.
