How does biodiversity contribute to sustainability of a habitat?
More species means more opportunities for survival during an ecological disaster.
More genetic variation means more opportunities for survival in a disease outbreak.
More variety of species means more opportunities for needed resources.
All of the Answers
What factor contributes most to the sustainability of a habitat?
Competition between large predators
Large variety of organisms
Presence of volcanic rock
Absence of bacterial species
Which of the following describes an interaction between a biotic factor and an abiotic factor?
A pair of birds build a nest in a tree.
A black bear uses a cave for a winter home.
A squirrel gathers nuts to store for winter.
A vulture eats the remains of a wild pig.
What is the function of xylem?
Help prevent water loss
Exchange gases with the atmosphere
Capture sunlight for photosynthesis

Why does biodiversity contribute to a habitat's sustainability?
More plants and animals in a habitat increases biomass, which is how habitats store energy,
More species, more competition, which sustains their population
Changing conditions harm one species and allowing others to survive.
Landforms are changing shape.
Which of the following most likely supports the most sustainable ecosystem?
The habitat with the most plants
The habitat with the greatest variety of living things
The habitat with the warmest temperature
The habitat with the greatest amount of consumers
