1. Homework on ecosystems Go through and highlight important information.
Tundra- mainly found between the Arctic Circle to about degrees North.
Cold, windy and dry conditions support low-growing plants easily damaged by development e.g. oil exploration and tourism.
Deciduous and coniferous forests- located roughly degrees North.
Deciduous trees shed their leaves in winter, but cone-bearing coniferous evergreen are better suited to colder climates.

Answer the Exam question
Temperate grassland- located degrees north and south of the equator and always inland.
Warm, dry summers and cold winters support grasses for grazing animals
Hot deserts- covering 5% of the Earth’s surface. High daytime temperatures and low night time temperatures. Very little rainfall restrict plant and animals to highly specialised species
Mediterranean- Hot, dry sunny summers and mild winters support olive groves and citrus fruits.
Tropical grassland (Savanna)- located between degrees north and south of the Equator.
Distinct wet and dry seasons support large herds of grazing animals and their predators.
Polar- located around the North and South Poles. Low temperatures -50c and dry conditions prohibit most plant and animal life.
Tropical rainforest-covering 6% of the Earth’s surface mainly close to the Equator.
High temperatures and heavy rainfall create ideal conditions for vegetation.
More than half of all plants and a quarter of all medicines originate here.
