NJSLA-S Life Science Review #1

Front

What do plant cells have that animal cells do not?

Back

Chloroplasts are organelles in plant cells that allow them to perform photosynthesis, converting sunlight into energy.

Front

What is the process by which evolution occurs due to genetic adaptations of a species?

Back

Natural selection is the process where organisms better adapted to their environment tend to survive and produce more offspring.

Front

What do plants need to grow effectively?

Back

Plants require water, sunlight, carbon dioxide, and fertilizer for optimal growth.

Front

What are organisms in trophic level 1 classified as?

Back

Producers are organisms that produce their own food, typically through photosynthesis.

Front

Which microscopic organisms are likely to use photosynthesis to produce their own food?

Back

Examples include algae and certain bacteria that can perform photosynthesis.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.

Front

What role do decomposers play in an ecosystem?

Back

Decomposers break down dead organic material, returning nutrients to the soil and helping to recycle matter in the ecosystem.

Front

What is the difference between primary and secondary consumers?

Back

Primary consumers eat producers (plants), while secondary consumers eat primary consumers.

Front

What is an example of a primary consumer?

Back

Herbivores, such as rabbits and deer, are primary consumers that eat plants.

Front

What is the significance of biodiversity in an ecosystem?

Back

Biodiversity contributes to ecosystem resilience, stability, and the ability to adapt to changes.
