A system of animals, plants and bacteria and it interrelated chemical and physical environment
1 of 18
Biome
Large scale ecosystem
2 of 18
Food Chain
A community of organisms where each member is eaten by another member
3 of 18
Latosol Soil
Tropical Rainforest - are red or yellowish in colour and have a thick litter layer but a thin humus layer
4 of 18
Brown Earth Soil
Deciduous Forest - are replenished with nutrients by leaf litter which accumulates in autumn
5 of 18
Grey Soils
Desert - have little/no organic content: made up of piece of rock and sand
6 of 18
Epiphytes
-The seeds are blown between the trunks of the tree and become trapped. They remain up in the canopy, so they don't have to fight for light and have an advantage
7 of 18
Lianans
They have flexible so they can twist around tree trunk to reach the sunlight. the smoothness of the bark makes it harder for plants to grow on them.
8 of 18
Drip-tip
Drip-tip has a larger surface so they can take in more water. The mod-rib helps cope with rainfall because it would lose the excess water ore else algae may grow.
9 of 18
Large Leaves and Waxy Cuticle
Large surface area means it can hold more water. The sunlight reflects on the leaves, which acts as sunscreen for photosynthesis (it attracts more sunlight because of its waxiness)
10 of 18
Buttress Roots
The roots are mainly above because the soil above is infertile (roots can grow 30 feet). It provides stability for emergent trees.
11 of 18
Caulifory
Thin trunks so it can grow quickly. When an open passage of sunlight appears, the caulifory trees will move in that direction. Fruits grow on the sides so animals can easily take it.

Ecotourism
Place that maintains the environment in a sustainable way, it also involves local people in making decisions that affect their land and living
13 of 18
Salinisation
Occurs when the water in the soil evaporates in high temperatures, drawing up salts from the the soil to the surface. These salts are toxic to many plants and makes land unusable
14 of 18
Quiver Trees
Water Storage - green succulent leaves/bloated branches. Branches - white powder reflects heat, thick vines with few pores (reduces evaporation). Trunk - self amputation so it cuts off and fills the stump so water is not lost via respiration
15 of 18
Desert Flowers
Dead Plants condense life and releases a few 100 seeds in its last act. Can wait lifeless for 1-20 years until rain - plant grow can happen in 2-3 weeks of plant growth. Urgent need for pollenation to reproduce seeds.

Saguaro Cactus (symbol of the desert)
Stem expands to capitvate water and can take in a tonne of water in a few days. Leaves become thawns and reduce surface area to reduce water loss and break up wind current to reduce air currents = still air. Thawns can also reduce surface area.

Xerophytic
Plants that can survive in dry environments
