What is the primary focus of ecosystem ecology?
Answer: The study of how energy flows and nutrients cycle within ecosystems
Ecosystem ecology focuses on understanding how energy moves through an ecosystem and how nutrients cycle between biotic and abiotic components.
Which of the following is an example of an abiotic factor in an ecosystem?
Answer: Water temperature
Abiotic factors are non-living components of an ecosystem, such as temperature, light, water, and minerals. Water temperature is an abiotic factor that can affect species distribution and behavior.
In an ecosystem, which process is responsible for the movement of energy from producers to consumers?
Answer: Trophic transfer
Trophic transfer refers to the flow of energy through the food chain, from primary producers (plants) to herbivores and then to higher-level consumers (carnivores and omnivores).
What is the primary source of energy for almost all ecosystems on Earth?
Answer: Sunlight
Sunlight is the primary source of energy for most ecosystems, which is captured by plants during photosynthesis and then transferred through the food chain.
Which of the following is an example of a nutrient cycle in an ecosystem?
Answer: The carbon cycle
The carbon cycle is a key nutrient cycle in ecosystems. It describes how carbon atoms move through the atmosphere, organisms, and the environment, playing a central role in regulating climate and supporting life.
