Ecosystems
Energy and biomass
Biochemical cycles
Climate/Biomes
Random
100

Estuaries are this kind of ecosystem

Marine
100

Risks from this pollutant include metabolic disorder and DNA damage 

Microplastics 

100

This refers to the length of time that one atom of carbon remains in a specific store

Residence time

100

This type of biome is the most productive 

Tropical rainforest

100

This type of forest is particularly effective at taking up carbon

Young forest

200

This is a natural property of ecosystems

Sustainability
200

This describes when non-biodegradable toxins can accumulate in the tissues of organisms

Bioaccumulation 

200

These deposits of carbon remain in equilibrium with the environment


Storages

200

The three cells of the tricellular model are the Polar Cell, The Ferrel Cell and this

The Hadley Cell 

200

There is more of this element in your body than there is carbon 

Oxygen 

300

This type of species helps to hold an ecosystem together 

Keystone species 

300

This describes things like clean air and water, food production, and climate regulation, which come from healthy ecosystems 

Ecosystem services

300

This involves planting large areas with only one crop species

Monoculture 

300

Rainfall is approximately in balance with the levels of evaporation in this biome

Grasslands

300

In this type of ecosystem, the pyramid of biomass is sometimes inverted 

Aquatic 

400

For most animals, this is between 0.1 and 1 E/MSY

Background extinction rate 

400

This is the second law of thermodynamics 

Energy cannot be created or destroyed 

400

This is an example of a transfer in the carbon cycle 

Herbivores feeding on producers, carnivores feeding on herbivores, other possible answers

400

These three abiotic factors distinguish biomes

Water, insolation, temperature 

400

This trophic level includes foxes and hawks

Tertiary consumers 

500

This biodiversity intactness index or less indicates an ecosystem is at risk of collapse 

30%

500

Imagine a plant (producer) grows 100 units of biomass (GP) through photosynthesis. The plant uses some of this energy, say 20 units, to maintain itself through cellular respiration. What is its NP? 

It's Net Productivity is 80 units of biomass. 

500

This occurs when marine organisms such as phytoplankton and algae use carbon dioxide for photosynthesis

Biological uptake

500

These types of adaptations reduce water loss in dry conditions

Xerophytic

500

Keystone species are very often at this trophic level 

Apex predators / tertiary consumers
