Ecosystems and Biodiversity

5. A relationship where one organism benefits at the expense of the other, like a tick feeding on a dog.
7. Animals or plant species that are at risk of becoming extinct because there are too few left in the wild.
8. When animals lose their natural home because of things like deforestation or pollution.
10. Harmful substances, like plastics or chemicals, that damage the environment.
13. Mammals Animals that live in or around the ocean and breathe air, such as whales, dolphins, and seals.
14. Using resources in a way that doesn’t harm the environment or reduce availability for future generations.
15. The variety of different plants, animals, and microorganisms in an ecosystem.
16. When oil is released into the ocean, often from ships or drilling rigs, harming marine life and ecosystems.
17. When animals eat plastic by mistake, which can harm their health or even kill them.
18. Long-term changes in the Earth's weather patterns, like rising temperatures, that affect ecosystems.
20. The ways humans interact with animals, either positively (helping them) or negatively (hurting them).

1. The protection and careful management of natural resources and wildlife to prevent harm.
2. Marine animals that are accidentally caught in fishing nets or traps, often harmed or killed.
3. Services Natural benefits that ecosystems provide, like clean air, water, and food.
4. A relationship where one organism benefits and the other is unaffected, like barnacles on a whale.
6. Non-native species that harm the ecosystem by competing with local species.
9. Catching too many fish or marine animals, which can harm the ecosystem and the species.
11. A collision between a ship and a marine animal, like a whale, often causing injury or death.
12. An area where human activities like fishing are limited or banned to protect marine life.
19. A relationship where both organisms benefit, like bees pollinating flowers.
