Question

drag each label to the correct location.
determine the stability of each ecosystem.
an ecosystem with
populations that mate
with unrelated species
an ecosystem that has
very few species at every
trophic level
an ecosystem with populations
that mate with only related
species
an ecosystem that has many
species at every trophic level

Explanation:

• Less Stable:
• An ecosystem that has very few species at every trophic level: With fewer species, there are fewer alternative food sources and less resilience to disturbances.
• An ecosystem with populations that mate with only related species: Limited genetic diversity can make the population more vulnerable to diseases and environmental changes.
• More Stable:
• An ecosystem with populations that mate with unrelated species: Increases genetic diversity, which helps in adaptation and survival.
• An ecosystem that has many species at every trophic level: Higher biodiversity provides more stability as there are multiple species to fill ecological roles and buffer against changes.

Answer:

• Less Stable: an ecosystem that has very few species at every trophic level, an ecosystem with populations that mate with only related species
• More Stable: an ecosystem with populations that mate with unrelated species, an ecosystem that has many species at every trophic level
