unit 2 - Biomes Flashcards
Rainforests definations
Dense anddiverse forest biomes with high annual rainfall, humitidty and warm temperature
Largest rainforest
Amazon rainforest
How much percent of the worlds oxygen does the amazon rainforest produce?
20%
How many speicies live in the amazon rainforest
30 million
Ranforests cover how much % of the earth, and what is one thing special about them
6%
even with such little percentage, they are home to over half the species of plants and animas in the world
How much land is being cut from amazon rainforest every minute and accoridng to who?
Accoridng to the world wide fund for nature, roughly 5 football pitches is cut down
Soil of rainforests
Nutrient poor due to rapid decomposition
Wildlife of rainforests
Extraordinary range of speicies incluing amphibians, reptiles, mamllas and birds
Climate of rainforests
Tropical climate with high rainfall, high humidity and high temperature
Zone of rainforests
Found in tropical regions near the equator
Vegetation of rainforests
Multi layerd forest with an adundance of plants including herbs, ferns, orchids and evergreen trees
Importance of rainforests
Helps reduce climate change and maintain global temperatre and help in carbon isloation
Threats of rainforests
Deforestation, logging and increased human activities
how to preserve rainforests
Preserve endangered speices
adpat local techniques
reduce humanacitivity
Ecosystem restoration
One keystone species of the Rainforest biome
Fig trees, they are a major source of food for herbivores and its non existence can severely impact the food chain
Who are the Caboclo People
An indigenous community in the Amazon rainforest which has a sustainable tree plating practice in which they know exactly when to plant a tree and in a specific pattern to ensure faster growth rate and better harvest.
NTFPs
Non timber forest products
Why do rainforests have so many plants even though they have nutrient poor soil
Because the majority of the plants quickly absorb the nutrients before they are washed away, essentially feeding themselves whenever needed
Marine Biome
Biome characterized by their saltwater environments and include oceans, seas and coral reefs
Soil, and Vegetation of Marine Biome
Soil is sandy, muddy and rich in minerals near coastal areas but often nutrient poor in deeper zones
The vegetation includes algae, seagrass, mangroves and coral symbionts
Name an indigenous community near the Great Barrier Reef
The Aboriginal and Torret Straight Islanders
They live on the islands between northern Queensland and Papua New Guinea. They are dedicated to preserve keystone species such as Turtles, Dugongs and Corals due to their cultural beliefs.
They also have sustainable fishing practices to not overfish during mating season. Maintain sacred sea knowledge, including navigation, weather patterns, and species behavior.
They also work with the Australian gov as part of the Reef 2050 plan to safe the Great Barrier Reef

Non Wood forest products
Problem faced by the great barrier reef
Coral bleaching
Ocean acidification
Overfishing (disturbs local communities and marine life)

Reef 2050 plan what is it?
Australia’s long-term strategy to protect and sustainably manage the Great Barrier Reef until 2050.
It focuses on improving water quality, restoring coral, tackling climate change, and involving Indigenous communities in reef protection.
The plan includes investments in science, conservation, and partnerships to ensure the reef’s health for future generations.
