I receive less than 25cm of rain per year. My soil is sandy and rocky. My animals are mostly nocturnal to avoid the scorching sun, and my plants have thick, waxy skins to store every drop of water. Who am I?
Desert
This biome includes oceans, rivers, lakes, wetlands and coral reefs. It can be made up of either freshwater or saltwater environments and is home to organisms such as fish, turtles, frogs, coral and aquatic plants. The amount of salt, sunlight, temperature and water depth influences which species can survive there.
What biome am I?
Aquatic
What are Biomes?
Biomes are large areas of land located around the world that are defined by their climate and soil.
I involve removing resources such as coal, metals and minerals from the ground. I can create jobs and provide important materials, but may also remove vegetation and disturb soil and habitats.
What human alteration am I?
Mining
Define Food Security
Food security: the availability and accessibility of food for all people.
I am hot and humid all year round. My soil is nutrient-poor, but I have the highest biodiversity on Earth. My plants have "drip tips" and "buttress roots" to survive the heavy rain. Who am I?
Tropical Rainforest
What plays the most important role in a Biome?
The climate
I involve changing natural environments into farmland for crops or livestock. I can provide food for people, but may also cause soil degradation, habitat loss and water pollution.
What human alteration am I?
Agriculture
Why is there uneven access to food?
There is uneven access to food because people and places have different levels of income, food production, transport, political stability and access to resources
I have very few trees because of my frequent fires and grazing animals. My soil is some of the richest and most fertile in the world, which is why humans use much of my land for farming. Who am I?
Savanna/ Grassland
This biome experiences four distinct seasons. Summers are warm, winters are cold, and there is usually moderate rainfall throughout the year. Many trees, such as oak, maple and beech, lose their leaves in autumn to conserve energy during winter.
What biome am I?
Deciduous forest.
What are Biotic Factors?
The living things and organisms in an ecosystem (e.g. plants, animals, bacteria).
I happen when trees and native vegetation are removed to make space for farms, roads, housing or industry. I can destroy habitats, increase soil erosion and reduce biodiversity.
What human alteration am I?
Land clearing
Name 3 threats to Food Security.
Water Scarcity, Climate Change, Threats from non-native plants, animals and insects, Competition for land, The use of land for fuel instead of food, Armed conflict
I am a "cold desert." My defining feature is permafrost—soil that stays frozen all year. Because of this, trees cannot grow here, so you’ll only find mosses and lichens. Who am I?
Tundra
This biome is found in places with hot, dry summers and mild, wet winters. Vegetation often includes small shrubs, grasses, olive-like trees and plants with thick or waxy leaves that help reduce water loss. It is common around the Mediterranean Sea, but similar environments are also found in parts of Australia, California and South Africa. Who am I?
Mediterranean biome
What are Abiotic Factors?
The non-living things that exist within an ecosystem (e.g. temperature, soil, air, sunlight, climate).
I involve supplying water to crops and farmland using systems such as canals, sprinklers or drip irrigation. I can increase food production in dry areas, but using too much water can reduce river flows, damage wetlands and increase soil salinity.
What human alteration am I?
Irrigation
What is Productivity in relation to biomes?
Productivity is the ability of a biome or area of land to produce food, plants or other natural resources over a period of time.
I am the world's largest land biome. I am dominated by coniferous trees (evergreens) that have needle-like leaves to shed heavy snow. My winters are long and very cold. Who am I?
Taiga (Boreal Rainforest)
What percentage of the Earth is covered by Aquatic (Freshwater) Biomes?
20%
