What happens to an ecosystem if a key species goes extinct?

Back

The extinction of a key species can disrupt the food chain and negatively impact the entire ecosystem, leading to a decline in biodiversity.

How can overfishing affect marine biodiversity?

Back

Overfishing can lead to the decline or extinction of certain fish species, which can disrupt the food web and decrease overall marine biodiversity.

Front

What is a food web?

Back

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

Front

What is the difference between a food web with low biodiversity and one with high biodiversity?

Back

A food web with low biodiversity is more vulnerable to disruptions, as the loss of one species can collapse the entire system, while a high biodiversity food web is more resilient.

Front

What factors contribute to high biodiversity in a habitat?

Back

Factors include a variety of ecological niches, availability of resources, stable environmental conditions, and minimal human impact.

Front

How does species richness relate to biodiversity?

Back

Species richness refers to the number of different species in a given area, and it is a key component of biodiversity.

Front

What is an example of a habitat with high biodiversity?

Back

A tropical rainforest, which contains a vast number of different species of plants, animals, and microorganisms.

Front

What role do producers play in a food web?

Back

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