Relationships in Nature 8th grade

What is an example of competition within a species?

• Lion cubs playing with each other

• Male lions fighting over a pride of lionesses

• Female lions hunting together

• Male lions grooming each other

Give an example of predation between different species.

• eagle capturing a fish

• lion hunting and consuming a zebra

• shark eating a seal

• snake preying on a rabbit

Name a mutualism example where both species benefit.

• Lions and zebras

• Bees and flowers

• Dogs and cats

• Trees and fungi

Explain the concept of parasitism relationships.

• Parasitism relationships involve a mutualistic interaction between two organisms.

• Parasitism relationships involve the host benefiting at the expense of the parasite.

• Parasitism relationships involve both organisms benefiting equally from each other.

• Parasitism relationships involve one organism benefiting at the expense of another, causing harm or weakening the host.

How do symbiotic interactions benefit both species involved?

• By causing harm and weakening the species involved

• By competing for resources and causing stress

• By spreading diseases and reducing population sizes

• By providing resources, protection, or other advantages that each species may not be able to obtain on its own.

How does competition within a species affect population growth?

• Competition within a species always leads to exponential population growth

• Competition within a species can decrease population growth by limiting resources and increasing death rates.

• Competition within a species results in decreased competition among individuals

• Competition within a species has no impact on population growth

Describe the role of predators in controlling prey populations.

• Predators control prey populations by hunting and consuming them.

• Predators control prey populations by teaching them to hide better.

• Predators control prey populations by befriending them.

• Predators control prey populations by organizing them into groups.

How do mutualistic relationships contribute to ecosystem stability?

• Mutualistic relationships decrease biodiversity

• Mutualistic relationships have no impact on nutrient cycling

• Mutualistic relationships make ecosystems more vulnerable to environmental changes

• Mutualistic relationships enhance nutrient cycling, increase biodiversity, and provide resilience to environmental changes.

Discuss the impact of parasites on the health of their hosts.

• Parasites only cause minor inconveniences for their hosts

• Parasites can negatively impact the health of their hosts by causing diseases, nutrient deficiencies, tissue damage, and weakening the immune system.

• Parasites do not affect the health of their hosts in any way

• Parasites have a positive impact on the health of their hosts by boosting immunity

Provide an example of a symbiotic relationship in nature.

• Trees and soil

• Lions and zebras

• Bees and flowers

• Sharks and dolphins
