OpenSciEd: Serengeti Part 2

Front

What is the energy transfer efficiency in a food chain?

Back

Energy transfer efficiency is typically around 10%, meaning that only about 10% of the energy from one trophic level is passed on to the next level.

Front

What is a tertiary consumer?

Back

A tertiary consumer is an organism that eats secondary consumers. They are typically at the top of the food chain and can be carnivores or omnivores.

Front

What is the bottleneck effect?

Back

The bottleneck effect occurs when a population's size is significantly reduced for at least one generation, leading to a loss of genetic diversity.

Front

How much energy does a chameleon receive if the leaf has 15,000 units of energy?

Back

The chameleon receives 150 units of energy, which is 1% of the energy from the leaf.

Front

Which biome is most likely to recover after a disturbance?

Back

Tropical & sub-tropical moist broadleaf forests are most likely to recover after disturbances like fire or drought.

Front

What is the primary role of producers in an ecosystem?

Back

Producers, such as plants, convert solar energy into chemical energy through photosynthesis, forming the base of the food chain.

Front

What is the significance of energy loss in a food chain?

Back

Energy loss at each trophic level limits the number of levels in a food chain and affects the population sizes of organisms.

Front

What factors can lead to a population bottleneck?

Back

Catastrophic events such as natural disasters, disease outbreaks, or human activities can lead to a population bottleneck.

Front

What is the difference between a food chain and a food web?

Back

A food chain is a linear sequence of organisms where each is eaten by the next, while a food web is a complex network of interconnected food chains.

Front

What is the role of a hawk in an ecosystem?

Back

A hawk is a tertiary consumer that helps control the population of smaller animals, maintaining balance in the ecosystem.
