What is a resource?
A resource is anything that organisms need to survive, such as food, water, and shelter.
100
What is an ecosystem?
An ecosystem is a community of living organisms interacting with each other and their environment.
100
What is a population?
A population is a group of individuals of the same species living in a specific area.
100
How can we collect data about populations?
Data can be collected through surveys, monitoring, and observation of species.
100
How do humans affect ecosystems?
Humans can alter ecosystems through activities like urban development, pollution, and agriculture.
200
How do resources affect populations?
The availability of resources can determine the size and health of populations; more resources can support larger populations
200
Name the three things that are essential to survival.
(F, W, S.)
Food, Water, and Shelter
200
What factors can limit population growth?
Factors include food availability, predators, disease, and habitat space.
200
What does a food web show?
A food web shows the complex feeding relationships between different organisms in an ecosystem.
200
What is overfishing?
Overfishing is the depletion of fish stocks due to catching fish at a rate faster than they can reproduce.
300
Name one renewable resource.
Solar, wind
300
What is competition?
Competition occurs when two or more organisms seek the same limited resources.
300
Define biodiversity.
Biodiversity refers to the variety of life in a particular habitat or ecosystem.
300
What is an ecological footprint?
An ecological footprint measures the impact of a person or community on the environment,
300
What is deforestation?
Deforestation is the clearing of forests for agriculture, urban development, or other uses.
400
What would happen if the snail went extinct?
All other animals would suffer a population loss.
400
What is the most common example of competition in animals?
Competition for mates.
400
How do invasive species affect ecosystems?
Invasive species can outcompete native species for resources, disrupting the ecosystem balance.
400
How can graphs help us understand populations?
Graphs can visually represent population trends over time, making it easier to analyze data
400
How does pollution impact organisms?
Pollutants can harm organisms by contaminating their habitats, affecting their health and survival.
500
How do predators influence resource availability?
Predators can help control the population of prey species, which affects the availability of resources like food and habitat.
500
Explain symbiosis.
Symbiosis is a close relationship between two different species that can be beneficial, harmful, or neutral.
500
What is mutualistic symbiosis?
This means that two animals of different species are interacting with a positive outcome for both.
500
Define habitat loss.
Habitat loss is the destruction or alteration of a natural environment, making it unsuitable for the species that live there.
500
Describe sustainable practices.
Sustainable practices are methods of using resources that meet current needs without compromising future generations' ability to meet their own needs.
