Habitats and ecosystems are communities of organisms - both plants and animals. An example is a grassland. Plants grow in the fertile soil and these attract insects who pollinate them. The insects attract predators, like birds, and these in turn attract larger predators. All of these are adapted to life on the grassland. In order to protect various species and encourage biodiversity, it is important for people and governments to protect habitats and ecosystems.

Science: Elementary School: Grades 3, 4 and 5 Quiz - Habitats and Ecosystems (Answers)

Which of the following is not an example of a habitat?

[ ]	Salt marshes
[x]	The United Kingdom
[ ]	A rainforest
[ ]	A hedgerow

While the United Kingdom has many inhabitants, or people who live in it, it is not a habitat

What is an ecosystem?

[ ]	An environmentally-friendly place to live
[ ]	A community which tries to live an ecological lifestyle
[x]	The interaction between a habitat, its community of species, and environmental conditions
[ ]	A recycling system

There are many different ecosystems

Which of these species could be found in a woodland environment?

[ ]	Lions
[ ]	Cacti
[ ]	Crocodiles
[x]	Fungi

Lions live in savannah, cacti in deserts and crocodiles in rivers

Which of the following might be found in an urban (city) habitat?

[ ]	Foxes
[ ]	Pigeons
[ ]	Squirrels
[x]	All of the above

The urban environment provides a home for many species besides humans

Which of the following does not describe the environmental conditions of a tidal (seaside) habitat?

[x]	Always wet
[ ]	Frequently windy
[ ]	Alternating between hot and cold
[ ]	Often rainy

One of the reasons the seaside is an extreme environment is the frequency with which conditions change - the tide covers the shore twice every day, but leaves it exposed to drying winds and sunshine twice every day as well

In which habitat might a newt be found?

[ ]	In the desert
[x]	Near a pond
[ ]	On the seashore
[ ]	In a coniferous forest

Newts are amphibians, like frogs and toads, and so need to be close to fresh water

All animals need food, shelter, water, oxygen and space to live. Which of these is hard to find in a grassland habitat?

[ ]	Oxygen
[ ]	Food
[x]	Shelter
[ ]	Space

Grassland is generally wide, open space

Woodlands and forests have layered habitats - different species inhabit different layers in these environments. What species might you find in the canopy layer of a woodland?

[ ]	Wild garlic
[ ]	Hedgehogs
[ ]	Earthworms
[x]	Sparrowhawks

The canopy is the uppermost layer in a woodland or forest habitat - where the treetops finally reach open space

Which of these species could be found in a desert habitat?

[x]	Snakes
[ ]	Holly
[ ]	Mosses
[ ]	Elephants

Holly and mosses are plants which need plenty of water so they are not found in deserts

10.

Which of these is a danger to marine habitats?

[ ]	Algae
[ ]	Killer whales
[x]	Rubbish
[ ]	Seaweed

Damage to a habitat affects the entire ecosystem - a huge amount of rubbish, especially plastic, ends up in the sea each year, endangering the species which live there
