Ecosystem Structure
A forest contains trees, deer, soil, water, and sunlight all interacting. What is this entire system called?
Ecosystem
A rainforest has thousands of different species of plants and animals. This describes its high level of what?
Biodiversity
A national park limits human activity to protect forests and wildlife. This is an example of:
Conservation
Two different species living closely together over time describes this general relationship.
Symbiosis
A group of deer living in the same forest at the same time is called a:
Population
In a pond, fish, algae, and insects make up this group of living components.
Biotic Factors
Lions in Africa that can reproduce with each other but not with tigers belong to this group.
Species
Energy from the sun and wind are examples of resources that can naturally replenish.
Renewable Resources
Bees get nectar while flowers get pollinated. This interaction is:
Mutualism
A coral reef has many species, each interacting and filling different roles. The reef’s stability depends heavily on this concept:
Biodiversity
Temperature, oxygen levels, and sunlight in a lake are examples of these.
Abiotic Factors
The dodo bird no longer exists anywhere on Earth. This is an example of what?
Extinction
Coal and oil take millions of years to form and are used faster than they are made.
Non-Renewable Resources
A barnacle attaches to a whale, benefiting while the whale is unaffected. This is:
Commensalism
If a disease wipes out all individuals of a species, the species has undergone:
Extinction
A scientist studies one single wolf in a pack. What level of organization is being observed?
Organism
Sea turtles are at risk of disappearing forever. What term describes their status?
Endangered Species
A cactus storing water to survive in the desert is an example of this survival trait.
Adaptation
A tick feeds on a dog’s blood, harming the dog. This is:
Parasitism
If a species has very little variation in traits, scientists say it has low:
Genetic Diversity
All the different populations of fish, plants, and microorganisms in a lake together form this.
Community
Within a population of beetles, some are green and some are brown due to DNA differences. This is known as:
Genetic Diversity
A polar bear’s physical environment—ice, snow, and Arctic conditions—is its:
Habitat
A hawk hunts during the day and eats small mammals, playing a specific role in its ecosystem. This role is its:
Niche
If an organism’s role changes, like becoming a top predator in a new environment, its ______ has changed.
