|
What does a plant need to create photosynthesis?
|
Carbon dioxide, water and sunlight
|
|
|
What happens if a population gets too big too fast?
|
There won't be enough food or space and the population will start dying off again.
|
|
|
Why are plants called producers?
|
They use energy, carbon dioxide and water to PRODUCE food (sugar).
|
|
|
What do scavengers do?
|
They eat animals that are already dead.
|
|
|
What do decomposers do?
|
They eat away or decompose any remaining dead material and converts it into nutrients for the soil. Some call them nature's recyclers!
|
|
|
What part of the plant captures sunlight?
|
chloroplasts (or chlorophyll)
|
|
|
What part of the plants has stomata that opens and closes to let IN carbon dioxide and let OUT oxygen?
|
Mainly the leaves
|
|
|
What would happen if there were no decomposers?
|
Nothing would put the nutrients back in the ground and then the plants wouldn't grow as big or as healthy.
|
|
|
What would happen if all the lions suddenly died?
|
The population of their prey would suddenly get bigger and bigger...
|
|
|
What do plants make in photosynthesis?
|
Sugar (food) and oxygen
|
|
|
How do plants get their water?
|
Through roots
|
|
|
What are abiotic factors?
|
Abiotic factors are nonliving parts of an ecosystem (e.g. light, air, water, land, temperature)
|
|
|
What are biotic factors?
|
Biotic factors are the living parts of an ecosystem and how they interact with each other. (e.g carnivores eating herbivores, etc)
|
|
|
What is a population?
|
The number of a type of animal or plant that lives in a certain area.
|
|
|
What is a community?
|
All the populations of different plants and animals living together in one area.
|
|
|
What is an organism?
|
A single animal or single plant
|
|
|
What is a food chain?
|
A line showing what eats what. (eg) grass-->zebra-->lion
|
|
|
What is a food web?
|
All the different food chains together in one community and how all the different organisms relate to each other. (e.g)
|
|
|
What is an omnivore?
|
An animal that eats bothe plants and animals.
|
|
|
What is an herbivore?
|
An animal that eats ONLY plants.
|
|
|
What is a carnivore?
|
An animal that ONLY eats meat (other animals).
|
|
|
Where does all the energy in the food web originally come from?
|
The sun
|
|
|
Which biome has four seasons and broadleaf trees that loose their leaves during the fall?
|
Deciduous forest
|
|
|
Which biome has long harsh winters, very little rainfall, and permafrost (permanently frozen ground - even in the summers!)?
|
Tundra
|
|
|
Which biome has the highest biodiversity (lots of different types of plants and animals), plentiful rain, and year-round warm temperatures?
|
Rainforest
|
|
|
Which biome is filled with pine needles, low nutrient soil, has a long cold winter, and tons of conifers (cone trees)?
|
Coniferous forest (Taiga)
|
|
|
Which biome has very few trees, strong winds and is mostly dominated by grasses?
|
Grassland
|
|
|
What is another word for an organism that uses photosynthesis to make their own food?
|
Producer
|
|
|
Which biome has very little rainfall, little available food, no shelter from the sun, high winds and extreme temperatures (very hot or very cold)?
|
Deserts
|
|
|
Which biome typically has two seasons: a growing season and a non-growing season (usually too cold or too dry)?
|
Grasslands
|
|
|
What is one limiting factor of deserts?
|
Answers can vary but the obvious one is water!
|
|
|
What is one limiting factor of rainforests?
|
Answers can vary but the obvious one is sunlight!
|
|
|
What is one limiting factor of grasslands?
|
Answers can vary but the obvious one is lack of food and water during the dry or nongrowing season.
|
|
|
What is one limiting factor of the tundra?
|
Answers can vary but the obvious one is cold temperatures.
|
|
|
What is one limiting factor in the coniferous forests?
|
Answers can vary but the best one is probably the very short summer growing season and the long cold winters.
|
|
|
What is one limiting factor in the Deciduous forests?
|
Answers can vary but the obvious one is the changing seasons. Plants and animals have to be able to adapt to these different extremes of temperatures.
