Question 1: An impact of this is Loss of biodiversity

Answer:

Many different species of plants and animals die because of deforestation. As plants and animals are closely connected through the food web, deforestation this reduces the biodiversity, or variety of species found in the tropical rainforest.

Question 2: Structure of a tropical rain forest

Answer:

?ground level ?shrub layer ?under canopy ?(main) canopy ?emergents

Question 3: Buttress roots are

Answer:

large roots have ridges which create a large surface area that help to support large trees.

Question 4: what does the term Biotic mean?

Answer:

Biotic factors are living condition which can influence where plants or animals live. It is the activity of a

living organism that affects another living organism within its environment:

?Competition for food ?Predator - prey relationships ?Parasitism ?Disease

Question 5: Threats from farming

Answer:

large areas are cleared for pastoral farming. As the global demand for meat has increased many cattle farms have opened in the Amazon Basin for beef farming. Arable farming is also responsible for the loss of tropical rainforest as many farmers are clearing land to grow cash crops, such as soya beans.

Question 6: Tree trunks are

Answer:

these are tall and thin to allow trees to reach the sunlight. The bark on these trees is smooth to allow water to flow down to the roots easily.

Question 7: Threats from Mining

Answer:

the Amazon Basin is rich in natural resources such as iron ore, copper, tin, aluminium, manganese and gold. This has led to the development of mines which results in the clearance of tropical rainforest.

Question 8: What does the term Abiotic mean?

Answer:

Abiotic factors are non-living conditions which can influence where plants or animals live: ?temperature ?light intensity ?moisture content of soil ?pH of the environment

Question 9: spider monkey adaptations

Answer:

long, strong limbs to help it to climb through the rainforest trees.

Question 10: Lianas are

Answer:

these are woody vines that have roots in the ground but climb up the trees to reach the sunlight. Their leaves and flowers grow in the canopy.

Question 11: Sustainable management of this is International agreements

Answer:

agreements to protect tropical rainforests have been made between different countries through debt-for-nature swaps. This is when a country which is owed money by another country cancels part of the debt if an agreement is made by the debtor country to ensure the conservation of its tropical rainforests.

Question 12: Threats from Roads

Answer:

the construction of access roads for farmers, loggers and miners results in large parts of the tropical rainforest being destroyed.

Question 13: Sloth adaptations

Answer:

uses camouflage and moves very slowly to make it difficult for predators to spot.

Question 14: Threats from Population

Answer:

population growth has resulted in the loss of tropical rainforest as land is cleared to build houses and infrastructure.

Question 15: Soil

Answer:

?Most of the soil is not very fertile.?A thin layer of fertile soil is found at the surface where the dead leaves decompose.?It is red in colour because it is rich in iron.?Due to heavy rainfall the nutrients are quickly washed out of the soil.

Question 16: Sustainable management of this is Ecotourism

Answer:

this encourages sustainable tourism that creates jobs for local people whilst ensuring that the money generated is used to protect and conserve the tropical rainforest for future generations to enjoy.

Question 17: Threats from Logging

Answer:

tropical rainforests are cut down so that valuable trees like mahogany can be accessed and sold for timber to make furniture. Other trees are cut down for making paper products.

Question 18: An impact of this is soil erosin

Answer:

Once the land is cleared of rainforest vegetation the soil is left bare. When it rains, the nutrients in the soil are washed away. The nutrient cycle stops because there are no plants or trees shedding leaves to replace the nutrients in the soil. The soil is no longer able to support plant life because it is not fertile.The roots of plants and trees no longer hold the soil together so it is easily eroded.

Question 19: Sustainable management of this is Education

Answer:

It is important that local people, businesses and politicians understand the true value of the tropical rainforest. Once they understand the value of biodiversity, particularly in terms of tourism, they will be more likely to want to protect it from deforestation.

Question 20: Plants and animals

Answer:

?The warm and very wet climate provides perfect conditions for plant growth.?The wide range of plant species supports many different animals, birds and insects.?Species have adapted to the conditions of the rain forest, eg trees and plants have shallow-reaching roots to absorb nutrients from the thin fertile layer in the soil.

Question 21: Threats from Hydroelectric power (HEP)

Answer:

The creation of HEP stations in the Amazon Basin has resulted in large areas of forest being flooded to create the reservoirs and dams. The flooding of the Balbina dam in Brazil resulted in the loss of 920 square miles of tropical rainforest.

Question 22: flying frog adaptations

Answer:

fully webbed hands and feet, and a flap of loose skin that stretches between its limbs, which allows it to glide from plant to plant.
