Food Webs and Energy Flow
What do we call organisms that make their own food using energy from the sun?
what are producers?
What is a limiting factor?
what is a resource that controls how large a population can grow?
What is an ecosystem?
What are living organisms and the physical environment together (abiotic + biotic factors)
What is an introduced species?
What is a species that is brought to an environment where it does not naturally live
What is Ms. Lee's favorite animal?
What is a manatee
In a food web, energy originally comes from what source?
What is the Sun?
Name two abiotic factors that can affect a population.
What are rainfall, sunlight, temperature, water, soil? (accept any two)
name the three types of relationships between organisms.
What are predation, competition and mutualism?
Why do introduced species often become invasive?
What is because they have few natural predators (top of food chain/eat everything) and can grow or reproduce quickly
Name one organim that is a decomposer
what are bacteria, fungi, or nematodes (earthworms ect.)
Name two organisms that would be consumers in a food web.
What are animals/herbivores/carnivores/omnivores (accept any two specific animals)
If a population has more food available, what will likely happen to the size of the population?
What is the population will grow/increase
A bird eats a worm. What type of relationship is this?
What is predation
Name on negative effect an invasive species can have on an ecosystem
What is outcompeting native species, causing extinctions, disrupting food webs, or changing the environment
What happens to matter when an organism dies?
What is decomposers break it down and return it to the soil and atmosphere?
What is the role of decomposers moving energy through an ecosystem?
What is breaking down dead organisms and returning nutrients to the soil?
Describe what happens to a population when its habitat becomes smaller.
What is the population will decrease because there is less space and fewer resources?
Two animals eat the same type of food. what type of relationship is this?
What is competition
What is one way scientists can try to control an invasive species
What is removing manually, using pesticides, introducing natural predators, or preventing future introductions
How is matter cycling different from energy flow in an ecosystem?
What is matter cycles continuously and is reused, while energy flows in one direction
When is Ms. Lee's Birthday?
What is August 2nd
A predator population decreases. What will likely happen to the prey population?
What is the prey population will increase
A flower is pollinated by a bee. The bee gets food and the flower gets pollinated. What type of symbiotic relationship is this?
How can a reintroduced species benefit an ecosystem?
What is restoring feeding relationships and helping the ecosystem return to balance?
Where do nutrients in the soil come from?
What is from decomposers breaking down dead organisms and waste
