Q

What are producers? (feeding relationships)

A

Q

What are consumers? (feeding relationships)

A

organisms that are heterotrophs and ingest food containing the sun’s energy, they rely on other organisms for their food

17
Q

What is commensalism? give an example (symbiotic relationships)

A

one species benefits, while the other species is neither helped nor harmed. example: an orchid taking shelter on a tree

18
Q

What is parasitism? give an example (symbiotic relationships)

A

one species (the parasite) benefits while the other species (the host) is harmed. example: tick feeding on a dog’s blood

19
Q

What is mutualism? give an example (symbiotic relationships)

A

both species rely on each other for survival and gain an advantage from the interaction. example: bees and flowers, bees collect nectar from flowers as a source of food, and in the process, they inadvertently transfer pollen from one flower to another, facilitating the reproduction of the plants.
