Habitat vs Niche
This is the place where an organism lives; it provides food, shelter, and mates.
What is a Habitat?
When organisms struggle for the same resource (like food or space), this is called _____.
What is competition?
Shoot to take away points from any team: When one organism eats another, this interaction is called _____.
What is Predation?
Pick a student to do 10 pushups to double points. A close, long-term interaction between two species is called _____.
What is Symbiosis?
Shoot to double your points: A factor that slows population growth by reducing survival or reproduction (like food, water, or space) is called a _____.
What is a Limiting Factor?
This describes an organism’s role or job in its environment, including how it gets food and interacts with others.
What is a Niche?
When individuals or species work together for mutual benefit (like hunting in packs), this is called _____.
What is cooperation?
Name two traits (adaptations) a predator might have that help it catch prey.
Answers can include: Sharp teeth, claws, can run fast, very strong, hunts in packs, good eyesight, etc.
Identify the three main types of symbiosis.
What is Mutualism, Commensalism, and parasitism?
Shoot to steal: Name two abiotic limiting factors that could affect plant growth.
Sunlight and water. Nutrients will also be acceptable.
DOUBLE POINT VALUE: Give one example that shows: name an animal, its habitat, and one thing that is part of its niche.
Answer could be: Lion, grasslands of Africa, Apex predator
Shoot and double your score: Provide one example of interspecific competition (between two species) and one example of intraspecific competition (within a species).
Lion and hyena trying to eat same food source.
Two dominant males competing for reproduction in the herd.
Describe one way prey species can avoid being eaten.
What is herding together? Keeping watch is an acceptable answer as well.
Shoot to remove the points from any team: Describe the mutualism example described in the Content Review in which both organisms benefit and explain the benefit for each.
What is Giraffe and oxpecker?
Describe how a drought can act as a limiting factor for animals living in a grassland.
It would kill off plant life which is a food source for many organisms.
Explain why two species can share the same habitat but not the same niche.
Could be: They live in the same area with the same resources but do not have the same job. Such as Lion and Elephant
Describe one way cooperation can increase survival for a species.
What is Lions hunting together?
Remove any teams points: Predict how removing a top predator from an ecosystem could affect the population of a prey species and plant life.
The prey numbers would increase and plant life would decrease because there are more prey eating plants now.
Explain how a parasitic relationship differs from predation.
Parasites feed off the host without the intention to kill. Predation means to kill the prey for consumption.
Provide two biotic limiting factors listed in the Content Review.
Shoot to Double Score: A species of bird feeds at night on insects while another feeds on the same insects during the day. Describe how their niche is different and how it reduces competition between them.
Their niche is specific to the time of day they eat the insects. They do not have to compete for the same food source.
Shoot to double score: Explain how competition can result in one species reducing its population or moving to a new area.
The losing male leaving the herd to find a new home.
Shoot to double: Explain how a predator-prey relationship can lead to evolutionary change in both species over many generations.
Acceptable answer: Animals adapt to become better hunters or learn how to survive and not be eaten by the predator.
Give a real-world example of commensalism described in the content review and explain why one species is not helped or harmed.
A barnacle lives on the shell of a clam. The barnacle (a filter feeder) has food brought to it when the clam moves in the water. The clam is not harmed by the barnacle.
Shoot to double your points: How are Limiting Factors and Carrying Capacity related?
Limiting factors determine the carrying capacity.
