Explain both types autotrophs

Photoautotroph: An organism which is able to use light energy to synthesize organic compounds.

Chemoautrotroph: An organism which is able to use chemical energy to synthesize organic materials.

100

Name all types of consumers

Herbivores, Omnivores, Carnivores, 

100

This is what the pyramid of energy measured by

Amount of energy in each trophic level of a food chain

100

These are the three types of interactions

Parasitism, Commensalism, mutualism

100

These factors affect photosynthesis

Temperature, Concentration of carbon dioxide, nutrients and amount of light.

200

This is primary productivity

The rate of production of new biomass per unit area by autotrophic organisms

200

This is a decomposer

Bacteria and fungi which break down dead organic matter and release the nutrients back into the environment

200
This how a pyramid of numbers is measured

The number of organisms in each trophic level of a food chain

200

This is symbiosis

A relationship between two or more organisms of different species which live physically close together

200

What is an extremophile

An organism that is adapted to survive extreme temperature, pressure, salinity or pH

300

These are the three layers of water and the depths they stop at

Photic zone (200m), Thermocline (1000m), Deep Water (5000m)

300

Name all trophic levels in order

1. Primary Producer

2. Primary Consumer

3. Secondary Consumer

4. Tertiary Consumer

5. Quaternary Consumer 

6. Apex Predator

300

This is the percentage of the trophic level of the tallest ball in the pyramid of energy

0.1%

300

Give an example of phoresis

A manta ray with two attached remora fish

300
These are ways in which productivity is measured

Rate of photosynthesis of producers

Rate of increase in the biomass of producers

Using satellite imagery to measure the amount of chlorophyll

400

What is a key feature of an apex predator

It has no natural enemies

400

Difference in a food web and a food chain

Food chain: A way to describe the feeding relationships between organisms


Food web: A way to show all the different feeding relationships in an ecosystem

400

This is a pyramid of biomass

A diagram that shows the biomass present in each trophic level of a food chain

400

Give an example of commensalism

Clownfish and anemones

400

This is eutrophication

The process by which a body of water becomes enriched in dissolved numbers that stimulate the growth of producers, usually resulting in the depletion of dissolved oxygen

500

This is how a dead zone is formed

algae die, sink to the bottom, and are decomposed by bacteria—a process that strips dissolved oxygen from the surrounding water. Dense algal blooms also block sunlight, which prevents underwater grasses from growing. In turn, the animals that depend on these grasses for food and shelter suffer, as well.

500

This is the definition of biomass

The mass of living material in area; it can be measured as dry mass

500

This is why pyramids of biomass are sometimes inverted

While organisms like phytoplankton are eaten very quickly, their reproduction rate is so high that they reproduce quickly enough to provide enough biomass to maintain the population of the consumers

500

Explain both types of parasites

Ectoparasite: A parasite, such as a flea or a louse, which lives on the outside of its host

Endoparasite: A parasite, such as a tapeworm, which lives inside the body of its host

500

This is the result of algal species producing toxins

The organisms that ingest them will be poisoned which will cause mass mortality in aquatic organisms such as dolphins, manatees and whales, as well as food poisoning in people who eat contaminated shellfish
