AICE Environmental Management Unit 4: Managing Ecosystems and Biodiversity

This set of flashcards covers key concepts, definitions, and processes related to ecosystems, biodiversity, and human impacts as outlined in the lecture notes.

What defines a biome?

A biome is a large ecological area characterized by similar climate, vegetation and soil type.

What are the characteristics of the Desert biome?

Arid climate with low precipitation, shallow and coarse soil, and drought-resistant plants.

What is the climate of a Tropical Rainforest?

Warm and humid climate throughout the year, receiving abundant rainfall.

What type of soil is found in Grasslands?

Deep, red-colored soil high in iron content.

Describe the climate of the Tundra biome.

Cold with extremely long winters, short summers, and generally low precipitation.

What is ecological succession?

The gradual and predictable changes in the composition and structure of an ecological community over time.

What is primary succession?

Occurs in areas with no previous community; pioneer species begin to colonize and form soil.

What is the difference between Gross Primary Production (GPP) and Net Primary Production (NPP)?

GPP is the total energy fixed by photosynthesis; NPP is GPP minus energy used in respiration.

What is biomass?

The collective mass of living matter in a given place or time.

What is ecological efficiency?

The efficiency of energy transfer between trophic levels.

What is a pyramid of energy?

A graphical representation showing the amount of energy available at each trophic level.

What is an invasive species?

Species introduced to a new environment that can outcompete native species due to lack of natural predators.

What are some benefits of conserving biodiversity?

Potential medicines, food, ecological services, and cultural values.

What is 'CITES'?

An international agreement that bans selling, hunting, or capturing of threatened or endangered species.

What are habitat reserves?

Protected areas designated for the importance of wildlife and biodiversity.

What are the main causes of biodiversity loss?

Habitat loss, invasive species, population growth, pollution, climate change, overconsumption.

What is the impact of climate change on the Amazon?

Deforestation, loss of biodiversity, and disruption of ecosystems.

What is the purpose of the Antarctic Treaty?

To prohibit military activity, protect the environment, and regulate activities such as fishing and tourism.
