What is phytoplankton zooplankton quizlet?
Phytoplankton is a plant plankton & Zooplankton is a animal plankton.
Which statement is an accurate description of a keystone species?
Which statement is an accurate description of a keystone species? A keystone species that is a predator controls the herbivore populations, which in turn maintains the plant populations and keeps balance.
What is it called when a single species is fighting over access to limited resources?
Intraspecific competition is an interaction in population ecology, whereby members of the same species compete for limited resources.
Which of the following is are an abiotic factor quizlet?
Abiotic factors are the non-living parts of an organism's habitat. Examples of abiotic factors are water, air, soil, sunlight, and minerals. Biotic factors are living or once-living organisms in the ecosystem.
What do most zooplankton eat?
Zooplankton occupy the centre of the open-water food web of most lakes. They eat bacteria and algae that form the base of the food web and, in turn, are heavily preyed upon by fish, insects and other zooplankton.
What is plankton What is the difference between phytoplankton and zooplankton quizlet?
What is the main difference between phytoplankton and zooplankton? Phytoplankton produces food via photosynthesis whereas zooplankton must eat food.
What is a keystone species quizlet?
A keystone species is a species that has a disproportionately large effect on its environment compared to its relative abundance. This differs from a foundation species because a foundation species is just usually a primary producer that dominates an ecosystem in abundance and influence.
What is a keystone species?
A keystone species is an organism that helps define an entire ecosystem. Without its keystone species, the ecosystem would be dramatically different or cease to exist altogether. Keystone species have low functional redundancy.
Why do we compete with each other in terms of resources and other things?
Organisms compete for the resources they need to survive– air, water, food, and space. In areas where these are sufficient, organisms live in comfortable co-existence, and in areas where resources are abundant, the ecosystem boasts high species richness (diversity).
What kind of relationship exists between multiple organisms who seek the same limited resource?
when multiple organisms seek the same limited resource, there relationship is said to be called competition.
What characteristics do fossil fuels soil and sunlight all share?
5.07 Midunit Test
| Question | Answer |
|---|---|

| 2. Is a synthetic diamond a natural resource? | No |
| 3. What makes a resource nonrenewable? | It is used at a rate faster than it can be replenished |
When a population becomes isolated from another over a long period of time?
Allopatric speciation occurs when one population separates into two geographically isolated populations. The geographic isolation prevents gene transfer and reproduction, allowing for genetic divergence between the two populations.
Is zooplankton a fish?
Frontiers | Zooplankton Are Not Fish: Improving Zooplankton Realism in Size-Spectrum Models Mediates Energy Transfer in Food Webs.
Are zooplankton carnivores?
Zooplankton may be herbivores or plant-eaters (eat phytoplankton), carnivores or meat eaters (eat other zooplankton) or omnivores, which eat both plants and animals (eat phytoplankton and zooplankton).
What is the main difference between phytoplankton and zooplankton?
Phytoplanktons and zooplanktons are two types of planktons that are found in water. Phytoplanktons are plants while zooplanktons are animals, this is the main difference between them. Larval Crustaceans, krills are examples of zooplanktons; algae and diatoms are examples of phytoplanktons.
What is a keystone predator quizlet?
Keystone species. Aplant or animal that plays a unique and crucial role in the way an ecosystem functions. Predator. A keystone species is often, but not always, this type of species, because they can Control the distribution and population of large numbers of prey species.
What is a keystone species worksheet answer?
A keystone species is a plant or animal that plays a unique and (1)crucial role in the way an ecosystem functions. Without keystone species, the ecosystem would be dramatically different or cease to exist altogether.
Are fish keystone species?
In some regions anadromous fishes in fresh water appear to be keystone food resources for vertebrate predators and scavengers, forging an ecologically significant link between aquatic and terrestrial ecosystems.
How are carrying capacity ecosystems and biodiversity interrelated with one another?
The carrying capacity of an ecosystem is related to the biodiversity. The greater the biodiversity, the more stability in an ecosystem allowing for a stable carrying capacity.
How does competition over limited resources occur?
Competition occurs when two species each require a resource that is in short supply, so that the availability of the resource to one species is negatively influenced by the presence of the other species.
What is competition science?
Competition is most typically considered the interaction of individuals that vie for a common resource that is in limited supply, but more generally can be defined as the direct or indirect interaction of organisms that leads to a change in fitness when the organisms share the same resource.
What is occurring in the region around the Chilkat River in Alaska that allows chum salmon to spawn during the winter months?
What is occurring in the region around the Chilkat River in Alaska that allows chum salmon to spawn during the winter months? Thermal springs heat and break up the ice.
What kind of interaction occurs when two Cardinals are trying to build a nest in the same tree?
What kind of interaction occurs when two cardinals (birds of the same species) are trying to build a nest in the same tree? When two members of the same species compete for the same resource, it is called intraspecific competition.
What is gold an example of a fossil fuel a renewable resource a nonrenewable resource a natural pollutant?
Fossil fuels: includes crude oil/petroleum, natural gas, and coal. All fossil fuels are nonrenewable resources, but not all nonrenewable resources are fossil fuels. Nuclear fuels: refers to uranium and plutonium. Minerals and metals ores: includes diamond, gold, silver, copper, iron, aluminum, and all other minerals.
Why are fossil fuels considered nonrenewable resources quizlet?
Since fossil fuels takes hundreds of millions of years to form, they are considered nonrenewable resources.
What is the dominant organism colonize bare rock during primary succession?
Primary succession begins in barren areas, such as on bare rock exposed by a retreating glacier. The first inhabitants are lichens or plants—those that can survive in such an environment. Over hundreds of years these “pioneer species” convert the rock into soil that can support simple plants such as grasses.
What does geographic isolation cause speciation apex?
Answer and Explanation: Geographic isolation causes speciation because the animals isolated in a specific location form an isolated breeding population.
Are zooplankton secondary consumers?
Zooplankton are the animal-like primary consumers of plankton communities. In turn, zooplankton then become food for larger, secondary consumers such as fish. Zooplankton include microscopic and macroscopic organisms.
Are zooplankton herbivores?
Zooplankton may be herbivores or plant-eaters (eat phytoplankton), carnivores or meat eaters (eat other zooplankton) or omnivores, which eat both plants and animals (eat phytoplankton and zooplankton).
What small fish eat zooplankton?
Small Predators Mollusks, small crustaceans (such as shrimp and krill) and small fish like sardines and herring eat large amounts of the zooplankton.
