The Carbon Cycle
100

This term describes a community of living organisms interacting with their physical environment.

What is an ecosystem?

100

This law states that energy transformations are inefficient, with some energy lost as heat.

What is the second law of thermodynamics?

100
The environment provides trillions of dollars with of value with these.
What are ecosystem services?
100

This cycle involves the movement of phosphates through rocks, water, and organisms.

What is the phosphorus cycle?

100

Burning of these is leading to a large increase in the amount of CO2 in the atmosphere.

What are fossil fuels?

200

This species has a disproportionately large effect on its environment relative to its abundance.

What is a keystone species?

200

This process converts sunlight into chemical energy, while this other process releases energy from food. (2 answers)

What are photosynthesis and respiration?

200

This process leads to the formation of new species over time (speciation).

What is evolution through natural selection?

200

This acronym is used to remember the different elements that make up life. 

What is CHNOPS?

200

This process breaks down organic matter and releases carbon back into the atmosphere.

What is decomposition?

300

This type of niche is limited by competition and environmental pressures.

What is a realized niche?

300

Only about this percentage of energy is transferred from one trophic level to the next.

What is 10%?

300

Greater biodiversity generally makes ecosystems more this.

What is resilient or stable?

300

Unlike energy, this is recycled through ecosystems.

What is matter?

300

These marine structures store carbon and are part of the long-term carbon cycle.

What are shells or calcium carbonate deposits? 

400

This phenomenon occurs where two ecosystems transition into each other.

What is the edge effect?

400

This is the total amount of energy captured by producers, while this is the energy available to consumers after respiration. (2 answers)

 What are GPP and NPP?

400

Pollination, and water filtration are examples of this type of ecosystem service.

What is regulating?

400

This cycle includes volcanic emissions and the formation of acid rain.

What is the sulfur cycle?

400

These geological features release carbon dioxide into the atmosphere naturally.

What are volcanoes?

500

Biomes with a low number of this ecological concept, tend to have low levels of biodiversity.

What is a niche?

500

This concept explains why higher trophic levels have less biomass.

What is ecological efficiency?

500

This process increases genetic diversity and ecosystem resilience

What is speciation?

500

This process results from nutrient overload in aquatic systems, leading to algal blooms.

What is eutrophication?

500

This environmental concept, was introduced by fossil fuel companies to move the focus of environmental change to the individual, rather than the companies themselves.

What is a Carbon Footprint?
