Environmental Factors and Organization
Photosynthesis, water, sunlight, and weather in the Serengeti fall into this nonliving classification of ecosystem components
What is abiotic factors
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
This single sugar unit serves as the basic monomer for carbohydrates
What is monosaccharide
Factors that limit population growth based on how crowded or dense the population is are classified as this type
What is density-dependent factors
This term describes a living organism that is non-native to an ecosystem, spreads quickly, and causes environmental harm
What is invasive species
This level of organization refers to a group of the same species living together in one area.
What is a population
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
Carbohydrates are the very first macromolecule broken down by your body when it needs this
What is energy
A severe drought in the Serengeti is an example of this sub-category of density-independent factors.
What is weather
Proactive planning meant to avoid the unnecessary use or destruction of natural materials is called this
What is conservation
Organisms that can produce their own nutritions are classified as this ecological role.
What is autotroph
A mosquito feeding on human blood or a parasite harming its host represents this +/- biological interaction.
What is parasitism
Lipids serve this primary functional role regarding energy storage
What is long-term energy
This density-dependent factor occurs when individuals in a population fight over scarce resources like grass or water
What is competition
An ecosystem's capacity to maintain its structure and function over time despite changes is defined as this
What is stability/resilience
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
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
This chain-like molecule is the polymer form of a protein.
What is polypeptide
When resources are scarce, population growth levels off into an S-shaped curve known as this type of growth
What is logistic growth
Breaking apart a large, connected natural habitat into smaller, isolated patches is called habitat this
What is fragmentation
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
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
Nucleic acids carry and transmit this vital information within living organisms
What is genetic information
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
This practice occurs when a renewable resource is harvested to the point that it cannot naturally recover within a single generation
