Answer 8

When nutrients are washed out of the soil by water moving through it

Question 9

Tertiary consumers

Answer 9

A carnivore at the top most level in a food chain that feeds on other carnivores; An animal that feeds only on the secondary consumers

Question 10

Secondary consumers

Answer 10

Primary consumers. Can be classified into one or two groups. Carnivores (eat meat), omnivores (eat meats & plants)

A Detra Voors is an organism that eats dead or decaying plants or animals as food. detrivores include micro organisms such as bacteria and larger organisms such as fungi, insects, worms.

Question 14

Decomposers

Answer 14

An organism, usually a bacterium or fungus, that breaks down the cells of dead plants and animals into simpler substances

Question 15

Creating a wilderness

Answer 15

An area undisturbed human activity (it is banned)

Question 16

National park

Answer 16

An area mostly in natural state that is managed to protect biodiversity

Question 17

Sustainable forestry

Answer 17

Ways of harvesting forest without damaging it in the long-term

Question 18

Geographical conflict

Answer 18

Disagreement and differences of opinion linked to the use of places
and resources

Question 19

Sustainable forest management

Answer 19

This is about conserving forests by ensuring they are not used faster than
thev can be renewed.

Question 20

Agroforestry

Answer 20

Growing trees and crops together. Some crops benefit from the shelter
of the tree canopy. Trees also prevent soil erosion and crops benefit
from the nutrients in the leaf litter.

Question 21

Clearcutting

Answer 21

This is the logging of all trees in a wide area of forest.

Question 22

Selective logging

Answer 22

Trees are only cut down when they reach a certain height. Young trees
are allowed to mature so the height of the canopy is maintained. It only
moves large, valuable trees and leaves some of the forest intact.

Question 23

Afforestation

Answer 23

The replanting of trees to replace the original, primary forest that has
been lost. This method does not maintain the biodiversity of a natural
forest.

Question 24

Protecting areas

Answer 24

Just like in Costa Rica, this is simply about giving places legal protection
and enacting tight laws that stop deforestation in certain places.

Question 25

Sustainability

Answer 25

Sustainability ensures that future generations can access the environment, while current generations use it effectively for social, economic and environmental gain

Question 26

CITES

Answer 26

The Convention on international trade in endangered species CITES bans cross-border trade in certain species

Question 27

REDD

Answer 27

RED - Reducing emissions from deforestation and forest degradation A United Nations project whose purpose it is to stop deforestation

Question 28

Sustainable forest management

Answer 28

This is about conserving forests by ensuring they are not used faster than they can be renewed.

Question 29

Agroforestry

Answer 29

Growing trees and crops together. Some crops benefit from the shelter of the tree canopy. Trees also prevent soil erosion and crops benefit from the nutrients in the leaf litter.

Question 30

Monitoring

Answer 30

Satellite technology and photos are used to ensure that no illegal activities are taking place and that landowners follow guidelines for sustainability.

Question 31

Indirect threat

Answer 31

Caused by global warming/pollution - e.g. increased CO2 levels

Question 32

Intact forests

Answer 32

These are primary forests that have never been deforested.

Question 33

Direct threat

Answer 33

clear link between one thing happening and the damage being caused to something else - deliberately cutting down trees

Question 34

Taiga or boreal forest

Answer 34

Taiga is Russian for forest. The world's largest biome made up on coniferous trees that have adapted to a cold climate. It has a n extreme subarctic climate. Biodiversity is low

Question 35

Biodiversity

Answer 35

 The variety of plant and animal life in the world or in a particular habitat, a high level of which is usually considered to be important and desirable

Question 36

Net primary productivity

Answer 36

This is a measure of how much new plant and animal growth or biomass is added to a biome each year. It is measured in grams per square metre per year
