module 2 quizzes

It is based on the law of conservation of energy, that states "Energy is neither created nor destroyed, but it can only be transformed from one form to another form."

• 2nd Law of thermodynamics

• 1st law of thermodynamics

• energy

• ecosystem

Answer explanation

The First Law of Thermodynamics states that energy cannot be created or destroyed; it can only be converted from one form to another.

With each successive energy transfer or transformation in a system, less energy is available to do work.

• entropy

• disorder

• 2nd law of thermodynamics

• 1st law of thermodynamics

Answer explanation

The second law states that if the physical process is irreversible, the combined entropy of the system and the environment must increase.

a graphical representation of the energy found within the trophic levels of an ecosystem.

• food pyramid

• biotic system

• ecosystem

• energy pyramid

Answer explanation

energy pyramid shows the flow of energy at different trophic levels in an ecosystem

a hierarchical series of organisms each dependent on the next as a source of food

• food web

• food chain

• energy flow

• system

Answer explanation

food chain, in ecology, the sequence of transfers of matter and energy in the form of food from organism to organism.

Organisms that make up the first level of every food chain. Maker of their own food.

• first level consumer

• second level consumer

• tertiary consumer

• producer

Answer explanation

Producers are any kind of green plant. Green plants make their food by taking sunlight and using the energy to make sugar.

carnivores that feed on the primary consumers or herbivores

Answer explanation

Secondary consumers are largely carnivores that feed on the primary consumers or herbivores. They are heterotrophs, specifically carnivores and omnivores.

usually at the top of food chains, capable of feeding on secondary consumers and primary consumers

• Third level consumer

• Second level consumer

• first level consumer

• producer

Answer explanation

a carnivore at the topmost level in a food chain that feeds on other carnivores

make up the second trophic level. They are also called herbivores

• first level consumer

• second level consumer

• third level consumer

• producer

Answer explanation

Primary consumers make up the second trophic level. They are also called herbivores. They eat primary producers—plants or algae—and nothing else. For example, a grasshopper living in the Everglades is a primary consumer

A process used by plants and other organisms to convert light energy into chemical energy.

• photosynthesis

• energy transferred

• conservation

• conversion

Answer explanation

Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.

it is similar to a food chain but the it is comparatively larger than a food chain. Occasionally, a single organism is consumed by many predators or it consumes several other organisms.

Answer explanation

A food web consists of all the food chains in a single ecosystem
