Exploring Ecology and Biomes

What does the term 'biotic' refer to in environmental science?

• Non-living elements like rocks and water

• Living organisms only

• Both living and once-living material

• Atmospheric elements only

Which interaction involves one organism benefiting at the expense of another?

• Mutualism

• Commensalism

• Parasitism

• Resource partitioning

Which type of symbiosis benefits both interacting species?

• Mutualism

• Parasitism

• Predation

• Commensalism

What is the primary result of resource partitioning among species?

• Increased competition

• Decreased biodiversity

• Specialized adaptations

• Uniform use of resources

What is a fundamental niche?

• The potential range a species can occupy without competition

• The actual area a species occupies

• A niche forced upon a species due to competition

• The role a species actually plays in the ecosystem

What is the effect of competition on a species' niche?

• It expands the niche to new territories

• It has no significant effect

• It may shrink the niche due to competitive exclusion

• It increases the species' adaptability

Which biome is characterized by very low temperatures and low precipitation?

• Tropical rainforest

• Desert

• Tundra

• Temperate forest

What factor primarily drives the identity of a biome?

• Climate

• Soil type

• Altitude

• Biodiversity

Which zone in a freshwater biome does not receive sunlight?

• Littoral zone

• Limnetic zone

• Aphotic zone

• Benthic zone

What is the primary role of marine biomes in global ecology?

• Supporting agricultural development

• Regulating freshwater cycles

• Producing over 50% of the world's oxygen

• Providing habitats for terrestrial species
