What is an energy pyramid?

Back

An energy pyramid is a graphical representation that shows the flow of energy through different trophic levels in an ecosystem, illustrating how energy decreases as it moves from producers to top consumers.

Front

How much energy is typically available at the second trophic level if 10,000 joules are available at the first level?

Back

1,000 joules, as only about 10% of the energy is transferred to the next trophic level.

Front

What happens to the food web if a primary producer, like seagrass, dies?

Back

The energy available will not be sufficient to sustain the remaining organisms, leading to a potential collapse of the food web.

Front

What is carrying capacity in an ecosystem?

Back

Carrying capacity is the maximum number of individuals of a species that an environment can sustainably support without degrading the habitat.

Front

What is the abyssal zone?

Back

The abyssal zone is a deep oceanic zone located about 9,000 meters below the surface, characterized by extreme conditions such as cold temperatures and no light.

Front

What types of organisms can survive in the abyssal zone?

Back

Organisms that can survive cold temperatures and no light, often adapted to high pressure and low food availability.

Front

What is a food web?

Back

A food web is a complex network of feeding relationships among various organisms in an ecosystem, showing how energy and nutrients flow through the system.

Front

What is the role of producers in an ecosystem?

Back

Producers, such as plants and algae, convert sunlight into energy through photosynthesis, forming the base of the food web.

Front

What is the significance of documenting the ocean floor before and after fishing?

Back

Documenting the ocean floor helps assess the environmental impact of fishing practices and supports claims about the sustainability of different trap designs.

Front

What is the impact of limited nesting sites on a pigeon population?

Back

A lack of nesting sites can lead to a decline in the pigeon population as it restricts their ability to reproduce.
