ADP Ecosystems and Biodiversity Assessment

What is the primary factor that determines the size of a population in an ecosystem? (MS-LS2-1)

• Amount of resource
• Weather patterns
• Number of predator

How do changes in temperature affect organisms in an ecosystem? (MS-LS-2-1)

• They only affect animals
• They only affect plants
• They can change behavior and survival rates

How do organisms adapt to limited resources in their environment? (MS-LS2-1)

• They all die immediately
• They change or adapt immediately
• They compete or find alternatives

What evidence would support that an ecosystem is healthy? (MS-LS2-1)

• Only one species is thriving
• There is great biodiversity
• All predators are gone

Which statement best describes a mutualistic symbiotic relationship between organisms? (MS-LS2-2)

• A lion hunting a zebra
• A clownfish living in an anemone for protection
• Two birds competing for the same nest

How do invasive species typically affect an ecosystem? (MS-LS2-2)

• They compete with native species for resources like food or habitat
• They improve soil quality
• They reduce the predator population

What would most likely happen if all the predators were removed from an ecosystem? (MS-LS2-2)

• Plant populations would increase
• Prey populations would increase
• The ecosystem would be unchanged

Which interaction pattern represents competition? (MS-LS2-2)

• A bee pollinating a flower
• Two species of birds eating the same type of seed
• A rabbit eating grass

In a food web, which has the highest amount of energy? (MS-LS2-3)

• Producers
• Herbivores
• Carnivores

How does energy flow through an ecosystem? (MS-LS2-3)

• From consumers to producers
• Randomly between organisms
• From producers to consumers
