Habitats, biomes & food chains
Answers and reasoning. Review before teaching.
1. What term describes the non-living physical factors of an ecosystem (such as sunlight, temperature, water and soil): abiotic factors or biotic factors?
Abiotic factors
Abiotic factors are the non-living chemical and physical components of an environment.
2. Why do desert foxes (such as the fennec fox) have large ears with many blood vessels: to radiate excess body heat and listen for prey, or to swim?
To radiate excess body heat and listen for prey
Large ears act as thermal radiators in hot desert environments.
3. 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.
4. 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.
5. Which treeless polar biome has permanently frozen subsoil called permafrost: the Arctic tundra or the savanna?
Arctic tundra
Tundra ecosystems have cold temperatures, short growing seasons and permafrost.
6. 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.
7. 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.
8. 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.
9. 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.
10. How does a polar bear’s thick white coat help it survive in the Arctic: camouflage and insulation, or photosynthesis?
Camouflage and insulation
Thick fur and blubber trap body heat while white fur blends with snow and ice.
11. 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.
12. Why do many rainforest leaves have pointed “drip tips”: to shed heavy rainwater quickly, or to trap snow?
To shed heavy rainwater quickly
Drip tips allow water to run off rapidly, preventing fungal and algal growth on leaves.
