Compare Ecosystem Interactions - Middle School Life Science
- What is the ecological term for a relationship in which one benefits and the other is harmed?
- Parasitism. One organism benefits at the expense of the other's health.
- Which interaction is shown when two plant species in a desert both need scarce water?
- Competition. Both plants compete for the same limiting resource.
- Which interaction type is most similar across all ecosystems because every ecosystem has limited resources?
- Competition. All ecosystems have limited resources causing competition.
- Which interaction is shown when barnacles attach to a whale and the whale is unaffected?
- Commensalism. Barnacles gain transport and feeding opportunities.
- Which interaction is most likely to spread disease between species through close contact or feeding?
- Parasitism. Parasites spread diseases through host contact.
- Identify the interaction: a tick feeds on a deer and the deer loses blood and may get sick.
- Parasitism. The tick benefits while harming the deer host.
- Identify the interaction type: a remora rides a shark and gains food scraps; shark unaffected.
- Commensalism. Remora benefits from transport and food access.
- What is the definition of predation as an organism interaction?
- One organism kills and eats another organism. Predator gains energy while prey population is controlled.
- Which interaction is shown when a hawk catches and eats a mouse in grassland?
- Predation. Hawk is predator, mouse is prey in this food chain.
- What is the definition of mutualism as an organism interaction?
- Both species benefit from the interaction. Cooperation increases fitness for both partners.
- What pattern best compares competition across ecosystems such as forests, deserts, and oceans?
- Competition occurs in all ecosystems when resources are limited. Universal pattern when organisms need same resources.
- Which interaction is most likely to intensify during drought in a savanna ecosystem?
- Competition. Water scarcity increases resource competition.
- What is the definition of commensalism as an organism interaction?
- One species benefits and the other is unaffected. One-sided benefit with no harm or help to the other.
- Which interaction type is most directly linked to energy transfer between trophic levels?
- Predation. Energy flows from prey to predator in food chains.
- Identify the interaction: a remora rides a shark and eats scraps; the shark is not helped or harmed.
- Commensalism. The remora benefits without affecting the shark.
- What is the best comparison of parasitism across ecosystems such as freshwater, marine, and terrestrial?
- Parasitism occurs in all ecosystems; parasites depend on hosts for resources. Universal pattern; parasites exploit host resources.
- Which interaction type is most likely to be stronger in deserts where water is scarce?
- Competition. Limited water intensifies competition between species.
- Which interaction is shown when a tick feeds on a deer in a forest ecosystem?
- Parasitism. Tick benefits by taking blood while deer is harmed.
- What is the ecological term for a relationship in which both species benefit?
- Mutualism. Both organisms gain benefits from their interaction.
- What is the term for an interaction between organisms of the same species?
- Intraspecific interaction. Occurs within a single species population.
- What pattern best compares mutualism across ecosystems such as reefs, grasslands, and forests?
- Mutualism occurs in many ecosystems and increases survival or reproduction. Benefits both partners across diverse habitats.
- What is the ecological term for a relationship in which one benefits and the other is unaffected?
- Commensalism. One organism benefits while the other experiences no effect.
- Which interaction is shown when bees get nectar and flowers get pollinated?
- Mutualism. Both organisms gain resources they need to survive.
- What is the term for an organism that is hunted and eaten by another organism?
- Prey. An organism hunted by predators for food.
- What is the ecological term for an interaction in which both species are harmed by limited resources?
- Competition. Both organisms suffer when competing for the same scarce resources.
- Identify the interaction: a hawk catches and eats a mouse in a grassland ecosystem.
- Predation. The hawk kills and consumes the mouse for food.
- What is the definition of competition as an organism interaction?
- Organisms use the same limited resource, reducing access for others. Both organisms negatively affect each other's fitness.
- Identify the interaction type: clownfish live among anemone tentacles and both benefit.
- Mutualism. Fish gets protection, anemone gets cleaned.
- Which interaction best describes cleaner fish removing parasites from larger fish in a reef ecosystem?
- Mutualism. Both fish benefit: cleaners eat parasites, hosts get cleaned.
- Identify the interaction type: wolves hunt elk in a temperate forest food web.
- Predation. Wolves are predators that consume elk as prey.
- What is the definition of parasitism as an organism interaction?
- A parasite benefits while the host is harmed, usually not killed quickly. Long-term relationship where host provides resources.
- What is the term for an interaction between organisms of different species?
- Interspecific interaction. Occurs between members of different species.
- What is the ecological term for an interaction in which one organism kills and eats another organism?
- Predation. One organism consumes another for food.
- What is the term for an organism that hunts, kills, and eats another organism?
- Predator. An organism that hunts other organisms for food.
- Which interaction most directly increases plant reproduction when pollinators carry pollen?
- Mutualism. Both pollinator and plant benefit from the exchange.
- Identify the interaction: two bird species use the same nesting sites and both have fewer chicks.
- Competition. Both species suffer from sharing limited nest sites.
