Biodiversity
What is biodiversity?
Biodiversity refers to the variety of life on Earth, including the diversity of species, genetic differences within species, and the variety of ecosystems they form.
What is conservation?
Conservation is the careful use and protection of natural resources like water, trees, soil, and animals so they last for future generations.
What are limiting factors?
What are limiting factors?
Limiting factors are things in the environment that control how many plants or animals can live there.
What is human impact on the environment?
Human impact is the effect people have on nature through their actions, both positive and negative.
What is migration?
Migration is the movement of animals or people from one place to another, often to find food, better living conditions, or suitable climates.
Why is biodiversity important for humans?
Biodiversity provides essential services such as food, clean air and water, medicine, pollination of crops, and natural resources, while also supporting stable ecosystems that humans depend on.
Why do we need conservation?
We need conservation to keep the environment healthy, protect wildlife, and ensure resources don’t run out for people and nature.
Why are limiting factors important in nature?
They keep populations from growing too large and help maintain balance in ecosystems.
How do humans negatively impact the environment?
Activities like pollution, deforestation, overfishing, and burning fossil fuels harm ecosystems and wildlife.
Why do animals migrate?
Animals migrate to find food, escape cold weather, breed, or give birth in safer environments.
What are the main threats to biodiversity today?
Major threats include habitat destruction, climate change, pollution, overexploitation of resources, and the spread of invasive species.
How does conservation help humans?
Conservation provides clean air, safe drinking water, food, and medicines, and helps prevent natural disasters like floods or droughts.
What are examples of limiting factors?
Examples include food, water, shelter, space, weather, and predators.
What are examples of positive human impacts?
Positive impacts include recycling, protecting endangered species, planting trees, and creating national parks.
What are some examples of migrating animals?
Examples include birds flying south for winter, whales traveling to warmer waters, and monarch butterflies moving thousands of miles.
How can biodiversity loss affect ecosystems?
When species are lost, ecosystems can become less resilient, meaning they are less able to recover from disturbances like natural disasters, diseases, or climate shifts. This can lead to weaker ecosystem services for all life, including humans.
What are some ways people can practice conservation?
People can conserve by recycling, saving water, planting trees, using less energy, and protecting wildlife habitats.
How does food act as a limiting factor?
If there isn’t enough food, fewer animals can survive in that habitat.
How does pollution show human impact?
Pollution from factories, cars, and trash harms the air, water, soil, and the health of living things.
How does migration help animals survive?
Migration allows animals to reach places where they can find enough resources and safe conditions to live and reproduce.
What can people do to help conserve biodiversity?
Individuals can help by protecting natural habitats, supporting sustainable farming and fishing, reducing waste and pollution, planting native species, and advocating for conservation policies.
What happens if we do not conserve resources?
If we don’t conserve, many resources could disappear, animals may go extinct, and the environment could become unhealthy for humans too.
What happens if a limiting factor is removed?
A population may grow too quickly, which can upset the balance of the ecosystem.
Why is it important to reduce negative human impacts?
Reducing negative impacts helps protect the planet, ensure resources for the future, and keep ecosystems healthy.
Do humans migrate too?
Yes, humans migrate for reasons like better jobs, safety, education, or to escape natural disasters or conflict.
