Biology Semester 1 Review

Front

What is ocean acidification?

Back

Ocean acidification refers to the decrease in pH levels of the ocean caused by the absorption of excess carbon dioxide (CO2) from the atmosphere.

Front

What are the products of photosynthesis?

Back

The products of photosynthesis are glucose (sugar) and oxygen.

Front

What are the reactants of cellular respiration?

Back

The reactants of cellular respiration are glucose and oxygen.

Front

Define predation.

Back

Predation is an interaction where one organism (the predator) eats another organism (the prey) for food.

Front

What is a secondary consumer?

Back

A secondary consumer is an organism that eats primary consumers; they are typically carnivores or omnivores.

Front

What is the role of producers in an ecosystem?

Back

Producers, such as plants and phytoplankton, create their own food through photosynthesis and form the base of the food chain.

Front

What is the relationship between photosynthesis and cellular respiration?

Back

The products of photosynthesis (glucose and oxygen) are the reactants for cellular respiration, creating a cycle of energy transfer.

Front

What is biomass?

Back

Biomass refers to the total mass of living matter in a given area or volume, often measured in terms of energy content.

Front

What is the largest trophic level in terms of biomass?

Back

The largest amount of biomass in any ecosystem is found at the producer level.

Front

Define competition in ecology.

Back

Competition is an interaction between organisms where they vie for the same resources, such as food, space, or mates.
