During a many year study, researchers found only 1 breeding pair of Florida scrub jays per 25 acres of land (remained constant). Which is a limiting factor in the habitat that MOST likely prevents an increase in the number of scrub jays?

• the amount of food available in the area

• the suitability of male scrub jays as mates

• the number of daylight hours during breeding season

• the tendency of young scrub jays to remain in the same area

The diagram is a pyramid of biomass for a meadow ecosystem. The triangle shape of the diagram is useful for explaining which relationship among the trophic levels in this ecosystem?

• The amount of living organic matter is equal at all trophic levels in this ecosystem

• Third-level consumers in this ecosystem have the greatest amount of living organic matter

• With each step to a higher trophic level in this ecosystem, the amount of living organic matter increases

• Third-level consumers in this ecosystem provide living organic matter to producers and other consumers

• The amount of living organic matter decreases at each trophic level in this ecosystem
