What is the atmospheric gas that increases when fossil fuels are burned?

Back

Carbon dioxide (CO2) is released into the atmosphere when fossil fuels are burned, contributing to climate change.

Front

What is primary succession?

Back

Primary succession is the process of ecological change that occurs in an area where no soil exists, such as on new volcanic islands, starting with pioneer species.

Front

What is an algal bloom and what does it indicate?

Back

An algal bloom is a rapid increase in algae in water bodies, often indicating excess nutrients like phosphorus from fertilizer use.

Front

What is cellular respiration?

Back

Cellular respiration is a process in cells that converts glucose and oxygen into carbon dioxide, water, and energy (ATP).

Front

What is a herbivore?

Back

A herbivore is a consumer that eats only producers (plants), such as cows and rabbits.

Front

What is the role of pioneer species in an ecosystem?

Back

Pioneer species are the first organisms to colonize barren environments, initiating the process of ecological succession.

Front

What is the difference between autotrophs and heterotrophs?

Back

Autotrophs produce their own food (e.g., plants), while heterotrophs consume other organisms for energy.

Front

What is the significance of biodiversity in an ecosystem?

Back

Biodiversity enhances ecosystem resilience, productivity, and stability, providing various ecological services.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the warming of Earth's surface due to the trapping of heat by greenhouse gases like CO2 and methane.

Front

What are the main components of an ecosystem?

Back

The main components of an ecosystem include producers, consumers, decomposers, and the physical environment.
