What happens to organisms in an Eco-column if temperatures are too far above or below the optimal range?

Back

The number of organisms may decrease because they cannot survive the conditions.

Front

True or False: Detritivores like worms and isopods help the carbon cycle in the terrestrial chamber by adding nutrients to the soil.

Back

True

Front

Which temperature of water can hold more oxygen in aquatic chambers?

Back

COLDER WATER, because the H2O molecules move slower.

Front

What metric unit is used to measure the height of plants in the terrestrial column?

Back

centimeters

Front

True or False: Sensitive organisms like fish can become stressed when dissolved oxygen levels drop below 4 mg/L.

Back

True

Front

Define 'detritivores' in the context of an Eco-column.

Back

Detritivores are organisms that feed on dead organic matter, helping to decompose it and recycle nutrients back into the ecosystem.

Front

What is the role of photosynthesis in an Eco-column?

Back

Photosynthesis allows plants to convert sunlight into energy, producing oxygen and organic materials that support other organisms.

Front

Explain the carbon cycle as it relates to an Eco-column.

Back

The carbon cycle involves the movement of carbon through the atmosphere, soil, and living organisms, including processes like photosynthesis, respiration, and decomposition.

Front

What is the significance of measuring dissolved oxygen levels in aquatic chambers?

Back

Dissolved oxygen levels are crucial for the survival of aquatic organisms; low levels can lead to stress and death.

Front

How do temperature changes affect the solubility of oxygen in water?

Back

COLDER water can hold more dissolved oxygen than WARMER water because the molecules move slower, allowing more oxygen to be trapped.
