Species Interactions
A relationship where both species benefit, like bees pollinating flowers.
What is Mutualism
What type of organisms are at the base of an energy pyramid?
What are producers
What are the dependent factors that influence a populations decline?
What is disease, competition, food source, and habitat loss.
The invasive species Asian carp was accidentally introduced into Missouri rivers. They are fast-growing and consume a lot of food. What would happened to native fish like the paddlefish in Missouri?
What is their population would decline due to competition of resources?
What is lost to the environment at each trophic level in an energy pyramid?
What is heat?
A tick sucking a deer’s blood is an example of this type of symbiotic relationship.
What is Parasitism
The process that causes energy to decrease as it moves up trophic levels.
What is heat loss
Which human activity can lead to an increase in animal population?
What is habitat protection
What factors other than predator-prey interactions affected the deer and wolf populations in the learning activity from last week?
What is food availability and disease?
What organism should a student add to an aquarium to help remove nitrates?
What are plants or bacteria?
In a marine ecosystem, sea urchins eat algae. Sea otters eat sea urchins. If sea otters decline, what happens to algae?
What is decrease
Which organisms in a food web are considered primary consumers?
What are herbivores?
The monarch butterfly are migratory insects and are considered endangered. What human activity could be used to help increase the population with the least impact on the ecosystem?
What is establishing protected breeding and migration areas?
Which factors make invasive species dangerous to native species?
What is rapid reproduction, lack of predators, and competition for resources
What process in the nitrogen cycle helps bacteria return nitrogen to the atmosphere?
What is denitrification?
Prairie Dogs are a keystone species in the Midwest. They provide an important habitat for approximately 150 other organisms. Prairie Dogs are also a food source for predators like black-footed ferrets, hawks, and swift foxes. What happens if the prairie dogs are eradicated?
What is the ecosystem becomes unstable?
In a food chain, which level is most affected by biomagnification?
What is the quaternary consumer (Apex Predator)
Which of the following human activities helps reduce coral reef destruction caused by ocean acidification?
What is reducing fossil fuel use
What happens when a population exceeds its carrying capacity?
What is deaths outnumber births?
What human impact does increased CO₂ have on ocean ecosystems?
What is ocean acidification harming coral reefs?
What determines if the species interaction is mutualism, commensalism, or parasitism?
What is whether the effect is positive, neutral, or negative?
Why is an energy pyramid narrower at the top?
What is organisms at higher trophic levels receive less energy
How does oil dripping from cars harm the environment?
What is contaminating groundwater and killing microorganisms?
How did the introduction of Caulerpa algae affect Mediterranean biodiversity?
What is it reduced biodiversity by outcompeting native species?
How do Prairie dogs contribute to their ecosystem beyond serving as prey?
What is aerating soil and providing a habitat for other organisms?
