What type of climate is found in the tropical rainforest? (must name both factors)
consistently warm and high rainfall
What biome has low salt levels and includes rivers and ponds?
freshwater
Why are there many tadpoles in a pond ecosystem?
What are biotic factors and give one example?
living things, grass
How do the plants of the tundra survive?
adapted to drought and cold

estuary
What are the three main types of ecosystems found on Earth?
terrestrial, marine (ocean), and freshwater
What is the biome found in tropical latitudes and has grasses, shrubs and small trees?
savanna
Why is the soil of the temperate deciduous forest very fertile?
fallen leaves on the forest floor are decayed and nutrients are returned to the soil yearly
How can a grassland or savanna support so many carnivores?
they have a abundance of grasses and plants for herbivores to eat and the herbivores provide the carnivores with food
What is the largest aquatic marine ecosystem?
coral reef
What biome has the highest percentage of Earth's water?
ocean or marine
What is the most important factor to consider when deciding which biome is being described?
climate which includes temperature and precipitation
What biome has low tempertures, high winds and permantly frozen subsoil?
tundra
Which two biomes have the least amount of precipitation yearly?
tundra and desert
What is the reason that marshes have a lot of vegetation such as lily pads, bullrushes and reeds?
It is flat and mainly open with few trees.
Why are the day and night temperatures in the desert so extremely different?
low amount of water or moisture that allows heat to escape causing extreme differences in day and night temperatures
What is a negative effect of deforestation?
Habitat destruction
