Biotic & Abiotic
What is a biotic factor?
What is a living component of an ecosystem
What biome is characterized by low rainfall and cacti?
What is Desert
Rainforests have poor, nutrient-leached soil; grasslands have rich, fertile soil.
What is the sun
What is a primary consumer?
What is an organism that eats producers
What does NPP stand for?
What is Net Primary Productivity
Name one abiotic factor that affects aquatic ecosystems.
What is temperature, sunlight, salinity, or dissolved oxygen.
Which biome is the most biodiverse on land?
What is a Tropical rainforest.
What process do plants use to convert sunlight into energy?
What is photosythesis
What role do decomposers play in a food web?
What is they recycle nutrients by breaking down dead organisms.
Which biome has the highest NPP?
What is the Tropical Rainforest
Which is NOT a biotic factor: bacteria, sunlight, grass, fungi?
What is sunlight
Which biome has permafrost and very little precipitation?
What is a Tundra
What is the 10% rule in energy transfer?
What is only about 10% of the energy is passed to the next trophic level.
Give an example of a tertiary consumer.
What is a hawk that eats a snake that ate a mouse
What is the difference between GPP and NPP?
What is GPP is total energy captured; NPP is energy after respiration is subtracted.
How do abiotic factors influence biotic components?
What are they determining which organisms can survive and thrive in an environment?
Which biome is dominated by grasses and few trees?
What is Grassland
Why are there rarely more than 4–5 trophic levels in a food chain?
What is energy decreases significantly at each level.
What is the difference between a food chain and a food web?
What is a food chain is linear; a food web is a network of interconnected chains.
Why is NPP important in ecosystems?
What is determines the energy available to herbivores and higher trophic levels.
Describe an interaction between a biotic and abiotic factor.
What is a tree (biotic) uses sunlight (abiotic) for photosynthesis.
Compare the soil quality in a rainforest vs. grassland.
What is rainforests have poor, nutrient-leached soil; grasslands have rich, fertile soil.
What happens to the energy that isn’t transferred to the next level?
What is lost as heat through metabolism?
What would happen if a keystone species is removed from a food web?
What is it could cause the collapse or major changes in the ecosystem structure?
How do temperature and precipitation affect productivity?
What is more warmth and water typically increase productivity.
