Question

biodiversity & relationships (7 points)

1. mutualism

• definition: both species benefit from the relationship.
• example: bees and flowering plants — bees get nectar, and plants get pollinated.

1. commensalism

• definition: one species benefits, and the other is neither helped nor harmed.
• example: barnacles on whales — barnacles get transportation and access to food, while whales are unaffected.

1. parasitism

• definition: one species benefits at the expense of the other.
• example: ticks on mammals — ticks feed on blood, harming the host.

1. amensalism

• definition: one species is harmed while the other is unaffected.
• example: a large tree shading smaller plants — the tree is unaffected, but the smaller plants may struggle to grow.

1. neutralism

• definition: both species coexist without affecting each other.
• example: a spider and a cactus living in the same desert — they dont interact directly.

1. competition

• definition: both species are harmed as they compete for the same resources.
• example: two bird species competing for nesting sites.

1. describe symbiotic relationships you saw between organisms. (3 points)

organisms|interaction

Explanation:

Symbiotic relationships include mutualism (both benefit), commensalism (one benefits, other unaffected), parasitism (one benefits at other's expense), amensalism (one harmed, other unaffected), neutralism (no - effect on each other), and competition (both harmed). To describe symbiotic relationships between organisms, identify the organisms and match their interaction to one of these types.

Answer:

(No specific answer provided as no organisms are given in the question part. Student should fill in with real - life organism pairs and their corresponding symbiotic relationship type, e.g., "Bees and flowering plants, Mutualism")
