Revision for Living with the physical environment – Ecosystems and Tropical Rainforest Ecosystems: 1. What is an ecosystem? An ecosystem is

Epping Forest Ecosystem

This page focuses on Epping Forest as a case study of a small-scale ecosystem, which is valuable for understanding Epping forest ecosystem interdependence case study pdf.

Epping Forest is located northeast of London, at the junction of the M25 and M11 motorways in southeast England. It is classified as a deciduous woodland ecosystem.

The page presents a detailed food web for Epping Forest, showcasing the interdependence of species. It includes producers like deciduous trees and shrubs, and consumers such as rabbits, mice, birds, and foxes.

The seasonal adaptations of deciduous trees are explained, demonstrating how ecosystem components respond to environmental changes.

Vocabulary: Interdependence refers to the mutual reliance between different species in an ecosystem.

Example: In Epping Forest, foxes rely on rabbits for food, while rabbits depend on plants like grasses and herbs.

Highlight: The food web illustrates how energy flows through the ecosystem, from producers to various levels of consumers.

Ecosystem Balance and Change

This page delves into factors affecting ecosystem balance, which is crucial for answering GCSE geography ecosystems exam questions.

Ecosystems are sensitive to changes in both biotic and abiotic components. These changes can be caused by natural factors like droughts, fires, and floods, or human activities such as pollution, pesticide use, and deforestation.

The impact of species loss or gain on food webs is explained. For instance, the loss of a predator can lead to overpopulation of its prey, while the loss of a prey species can cause predator populations to decline.

The page also discusses methods for restoring ecosystem balance through management strategies like banning poaching, reforestation, and reducing fossil fuel use.

Example: If foxes were removed from Epping Forest, rabbit populations might increase, potentially leading to overgrazing of vegetation.

Highlight: Ecosystem management often involves addressing both direct threats (like poaching) and indirect threats (like climate change).

Vocabulary: Extinction refers to the complete disappearance of a species from Earth.

Global Ecosystem Distribution

This page examines the factors influencing the distribution of global ecosystems, which is essential for understanding biome definition Geography gcse.

Climate is identified as the primary factor determining ecosystem distribution. The amount of sunlight received at different latitudes explains why tropical rainforests are found near the equator, while polar regions have tundra ecosystems.

A world map illustrates the distribution of major biomes, including tundra, taiga, temperate deciduous forest, tropical rainforest, and desert.

The page also discusses the importance of altitude, relief, and ocean currents in shaping ecosystem characteristics. These factors can create local variations in climate, leading to diverse ecosystems within a region.

Definition: A biome is a large-scale ecosystem characterized by distinct plant and animal communities adapted to a particular climate.

Example: Tropical rainforests are found near the equator due to high levels of sunlight and rainfall throughout the year.

Highlight: The curvature of the Earth affects the intensity of sunlight received at different latitudes, influencing climate and ecosystem distribution.

Tropical Rainforest Characteristics

This page begins to explore the characteristics of tropical rainforests, which is crucial for understanding ecosystems GCSE geography Edexcel.

Tropical rainforests are found near the equator, where they receive intense sunlight and high levels of rainfall throughout the year. This climate supports a highly diverse ecosystem with unique adaptations.

The page likely discusses the structure of rainforests, including the different layers (emergent, canopy, understory, and forest floor) and the types of plants and animals found in each.

It may also touch on the importance of rainforests for global biodiversity and climate regulation, making them a critical focus of conservation efforts.

Vocabulary: Biodiversity refers to the variety of plant and animal life in a particular habitat or ecosystem.

Example: The Amazon Rainforest is home to an estimated 10% of all known species on Earth.

Highlight: Tropical rainforests are characterized by high temperatures, abundant rainfall, and incredible biodiversity.

Tropical Rainforest Characteristics

The fifth page details the physical characteristics and interdependence within tropical rainforests.

Vocabulary: Leaching refers to the process where heavy rainfall washes nutrients from the soil.

Highlight: Tropical rainforests maintain consistent temperatures between 20-28°C and receive approximately 2000mm of rainfall annually.

Example: The rainforest demonstrates complex interdependence between climate, water, soils, plants, and animals.

Deforestation Analysis

This section examines the causes and scale of tropical rainforest deforestation.

Definition: Deforestation is the large-scale clearance of forest areas.

Highlight: Approximately 10 million hectares of forest are lost annually worldwide.

Example: Both commercial farming for cattle grazing and subsistence farming for local food production contribute to deforestation.

Deforestation Impacts

The seventh page analyzes the various impacts of deforestation on the environment and economy.

Highlight: The Amazon rainforest stores approximately 140 billion tonnes of carbon.

Example: Brazil loses up to 100 tonnes of topsoil per hectare annually due to soil erosion.

Vocabulary: Carbon storage refers to the rainforest's ability to capture and retain carbon dioxide from the atmosphere.

Ecosystems Overview

This page introduces the fundamental concepts of ecosystems, which are crucial for understanding GCSE geography ecosystems exam questions.

An ecosystem is defined as a community of plants and animals interacting with each other and their physical environment. Ecosystems can be small-scale (e.g. a pond) or large-scale (e.g. Yellowstone Park).

The page explains how ecosystems function through food chains and webs. Plants act as producers, creating food through photosynthesis. Herbivores are primary consumers, while carnivores are secondary consumers.

The interconnections between biotic (living) and abiotic (non-living) components are highlighted. A detailed diagram of a pond ecosystem illustrates these relationships.

Definition: An ecosystem is a community of plants, animals and other organisms that interact with each other and their physical environment.

Example: A pond ecosystem includes producers like reeds, consumers like fish and birds, and decomposers like bacteria.

Highlight: Food chains show direct feeding relationships, while food webs demonstrate the complex hierarchy of feeding relationships in an ecosystem.
