Front

What is primary succession?

Back

Primary succession is the process of ecological change that occurs in an environment that has been newly formed or exposed, such as bare rock after a glacier retreats.

Front

What is the role of chloroplasts in plant cells?

Back

Chloroplasts are organelles in plant cells where photosynthesis takes place, converting light energy into chemical energy.

Front

Which organelle is responsible for producing ATP in cells?

Back

Mitochondria are the organelles responsible for producing energy in the form of ATP through cellular respiration.

Front

What macromolecule provides fast energy?

Back

Carbohydrates are macromolecules that provide quick energy for cellular functions.

Front

What is the order of ecological succession?

Back

The order of ecological succession typically follows a sequence from pioneer species to intermediate species and finally to a climax community.

Front

Define ecological succession.

Back

Ecological succession is the process by which ecosystems change and develop over time, involving a series of species replacements.

Front

What is the difference between primary and secondary succession?

Back

Primary succession occurs in lifeless areas where soil has not yet formed, while secondary succession occurs in areas where a disturbance has destroyed an existing ecosystem but soil and some organisms still remain.

Front

What is the function of the mitochondria?

Back

Mitochondria are known as the powerhouse of the cell, as they generate ATP through the process of cellular respiration.

Front

What are the products of photosynthesis?

Back

The products of photosynthesis are glucose and oxygen, produced from carbon dioxide and water using sunlight.

Front

What is a climax community?

Back

A climax community is a stable and mature ecological community that has reached a steady state of succession.
