Front

What is phytoplankton and its role in the ecosystem?

Back

Phytoplankton are microscopic organisms that live in water and perform photosynthesis, converting sunlight into energy. They are primary producers in aquatic ecosystems, forming the base of the food web.

Front

How do photosynthesis and cellular respiration differ in terms of energy?

Back

Photosynthesis stores solar energy in the chemical bonds of carbohydrates, while cellular respiration releases energy from these bonds to produce ATP molecules.

Front

What is the significance of reporting a sea turtle stranding?

Back

Reporting a sea turtle stranding is important because the information can help biologists and managers protect the species and understand the health of the ecosystem.

Front

What factors determine the carrying capacity of a species in an ecosystem?

Back

Biotic factors (like food availability and competition) and abiotic factors (like water, temperature, and habitat space) determine the carrying capacity of a species.

Front

What is artificial selection in agriculture?

Back

Artificial selection is the process by which humans breed plants and animals for specific traits, such as higher milk production in dairy cows.

Front

Define carrying capacity in an ecosystem.

Back

Carrying capacity is the maximum number of individuals of a species that an environment can sustainably support, determined by resource availability.

Front

What is the role of energy transfer in food webs?

Back

Energy transfer in food webs occurs when organisms consume one another, with energy moving from producers (like plants) to consumers (like animals) and eventually to decomposers.

Front

Explain the process of photosynthesis.

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy, using carbon dioxide and water to produce glucose and oxygen.

Front

What is the difference between biotic and abiotic factors?

Back

Biotic factors are living components of an ecosystem (like plants and animals), while abiotic factors are non-living components (like water, sunlight, and temperature).

Front

How does genetic diversity affect a population's resilience?

Back

Higher genetic diversity within a population increases its resilience to diseases, environmental changes, and other stressors, allowing for better adaptation.
