What is mass?

True or False: forms of energy can be transformed into different kinds of energy (e.g., light can be transformed into chemical energy). *

T or F: Ethanol (C2H5OH) has high energy bonds. *

T or F: Water (H2O) has high energy bonds. *

Both ethanol and water are clear liquids. Why does ethanol burn but water does not?

The basic building blocks of life are *

Carbohydrates, fats and proteins are examples of what?

the process in which glucose and oxygen molecules are rearranged into CO2and H2O to acquire chemical energy.

the process in which organisms use molecules they consume to make the macromolecules needed for its cells

a molecule that can efficiently deliver chemical energy to power cellular activity

T or F: both plant and animal cells contain DNA

T or F: a plants cell wall is made of cellulose

What happens during photosynthesis?

All carbon-based molecules in plants begin as

specialized proteins that enable molecular reactions to occur more quickly and easily are called

Enzymes in eukaryotic cells can rearrange glucose with what to form fatty acids and amino acids?

This consists of interactions between living species and the nonliving aspects of their environment

The atoms of all living organisms come from

What is biomass?

The capacity of an ecosystem to recover from a disturbance is known as...

biodiversity is..

If there is 10,000 kg of plant biomass, it could support ____ kg of primary consumer biomass.

Animals that consume other animals are _____

The organisms consumed by primary consumers are _____

T or F: The current rates of CO2 emission are higher than the amount absorbed through photosynthesis.

Gases like CO2 ________________ the loss of heat

Check all that are disturbances to ecosystems that are happening due to rising CO2 levels

This occurs when dissolved oxygen in aquatic ecosystems is reduced due to excess levels of nitrogen & phosphorus.

This refers to ecological disturbances resulting from excessive CO2 levels in the atmosphere due to human activity.
