Habitats, biomes & food chains
Answers and reasoning. Review before teaching.
1. What do we call a seasonal movement of animals (such as arctic terns or whales) from one region to another for feeding or breeding: migration or hibernation?
Migration
Migration is the regular seasonal journey between habitats.
2. What do we call a network of many interconnected food chains in an ecosystem: a food web or a rock cycle?
Food web
A food web shows the feeding relationships among multiple species in a community.
3. What term describes a close relationship in which two species both benefit (such as clownfish and sea anemones): mutualism or parasitism?
Mutualism
In mutualism, both partner species gain a survival benefit.
4. What is the role of fungi and bacteria that break down dead leaves and logs into soil nutrients: decomposers or apex predators?
Decomposers
Decomposers recycle nutrients back into the ecosystem.
5. Which biome near the Equator has warm temperatures, high rainfall year-round and the greatest terrestrial biodiversity: a tropical rainforest or a boreal taiga?
Tropical rainforest
Tropical rainforests support dense multi-layered canopies and high species diversity.
6. Which northern forest biome is dominated by cone-bearing evergreen trees such as spruce, fir and pine: boreal forest (taiga) or coral atoll?
Boreal forest (taiga)
The taiga (boreal forest) spans cold subarctic regions of North America and Eurasia.
7. Which warm, shallow marine habitat is built by tiny cnidarian polyps secreting calcium carbonate: a coral reef or a kelp forest?
Coral reef
Coral polyps build calcium carbonate skeletons that form coral reefs.
8. Which tropical grassland biome features scattered acacia trees and large herds of grazing mammals: savanna or temperate woodland?
Savanna
Savannas are warm grasslands with distinct wet and dry seasons.
9. Which coastal trees grow in tropical intertidal salt water using prop roots and salt-filtering tissues: mangroves or pines?
Mangroves
Mangroves stabilise coastlines and serve as nurseries for reef fish.
10. Which terrestrial biome receives very little rainfall (under 250 mm per year) and features plants like cacti with water-storing stems: a desert or a tundra?
Desert
Deserts are defined by aridity, and succulents store water in thick stems.
11. Which layer of a tropical rainforest receives the most direct sunlight above the main canopy: the emergent layer or the forest floor?
Emergent layer
Giant emergent trees rise above the main canopy into full sunlight.
12. Where a freshwater river meets and mixes with salty ocean water, forming a brackish coastal habitat, is called: an estuary or a glacier?
Estuary
Estuaries are productive brackish-water transition zones between river and sea.
