100

Photosynthesis, water, sunlight, and weather in the Serengeti fall into this nonliving classification of ecosystem components

What is abiotic factors

100

A bee pollinating a flower where both the bee gets food and the flower gets pollinated is an example of this type of symbiotic relationship where both species benefit.

What is Mutualism

100

This single sugar unit serves as the basic monomer for carbohydrates

What is monosaccharide

100

Factors that limit population growth based on how crowded or dense the population is are classified as this type

What is density-dependent factors

100

This term describes a living organism that is non-native to an ecosystem, spreads quickly, and causes environmental harm

What is invasive species

200

This level of organization refers to a group of the same species living together in one area.

What is a population

200

Barnacles riding on a whale get access to nutrient-rich waters while the whale remains unharmed. This describes what specific symbiotic relationship?

What is commensalism

200

Carbohydrates are the very first macromolecule broken down by your body when it needs this

What is energy

200

A severe drought in the Serengeti is an example of this sub-category of density-independent factors.

What is weather

200

Proactive planning meant to avoid the unnecessary use or destruction of natural materials is called this

What is conservation

300

Organisms that can produce their own nutritions are classified as this ecological role.

What is autotroph

300

A mosquito feeding on human blood or a parasite harming its host represents this +/- biological interaction.

What is parasitism

300

Lipids serve this primary functional role regarding energy storage

What is long-term energy

300

This density-dependent factor occurs when individuals in a population fight over scarce resources like grass or water

What is competition

300

An ecosystem's capacity to maintain its structure and function over time despite changes is defined as this

What is stability/resilience

400

While grass occupies the first trophic level as a primary producer, a red-tailed hawk preying on a field mouse (who eats grass) occupies this specific numerical trophic level.

What is a secondary consumer

400

In the Serengeti, lions actively attack and kill African wild dogs not to consume them for food, but to eliminate direct interference for shared prey species like gazelles. This aggressive, direct interaction between two apex predators competing over a shared food source represents this symbiotic relationship.

What is competition

400

This chain-like molecule is the polymer form of a protein.

What is polypeptide

400

When resources are scarce, population growth levels off into an S-shaped curve known as this type of growth

What is logistic growth

400

Breaking apart a large, connected natural habitat into smaller, isolated patches is called habitat this

What is fragmentation

500

Arranged from smallest to largest scale, this is the correct sequence of ecological levels of organization starting from an individual organism up to the global ecosystem

What is organism > population > community > ecosystem > biome > bioshpere

500

Sea otters control sea urchin populations to preserve kelp forests, grey wolves manage elk herds to allow willow growth, and prairie dogs build burrows that shelter species like burrowing owls. Because their presence holds an entire community together, these organisms represent this fundamental ecological concept

What is a keystone species

500

Nucleic acids carry and transmit this vital information within living organisms

What is genetic information

500

On a graph showing logistic growth, a population's size slows down and levels off once it reaches this threshold due to limited resources

What is carrying capacity

500

This practice occurs when a renewable resource is harvested to the point that it cannot naturally recover within a single generation

What is overexploitation (overharvesting)
