  1. 3. This is how your body keeps things stable inside, like making sure you're not too hot or too cold. It's like the thermostat in a house.
  2. 7. Cell: A more complex cell with a nucleus and other special parts. It's like a house with multiple rooms for different functions.
  3. 10. Reproduction: This is when it takes two living things (usually a mom and a dad) to make a new life. It's like mixing the traits of two different colored paints to create a new color.
  4. 11. This is a change in the DNA of an organism. Sometimes it's good, sometimes it's bad, and sometimes it doesn't matter. It's like a typo in a recipe; it could make the dish better, worse, or just different.
  5. 14. In nature, these are living things like plants that make their own food using sunlight. They're like the chefs in the food chain's kitchen.
  6. 15. These are animals and people who eat plants or other animals for energy. They're like the customers in a restaurant.
  7. 17. This is how your body turns food into energy and also how it builds and breaks down stuff in your cells. Imagine your body is like a factory, and metabolism is all the work happening inside.
  8. 18. These are organisms like fungi and bacteria that break down dead stuff and waste. Think of them as the clean-up crew.

  1. 1. Cell: This is a simple, single-celled organism without a nucleus or other special compartments. Think of it like a one-room apartment.
  2. 2. This is the ability to do work or cause change. It's like the fuel that powers machines or the food that powers you.
  3. 4. This is when two different kinds of living things help each other out in some way. Like bees getting nectar from flowers and helping the flowers spread their pollen.
  4. 5. In biology, this is when cells change to do specific jobs. It's like if a soccer team has goalkeepers, defenders, and strikers; each player has a different role.
  5. 6. Reproduction is when a living thing makes a copy of itself without needing a partner. Imagine you drew a picture, and then photocopied it.
  6. 8. The opposite of catabolism; this is when your body builds things up. Like when you take LEGO pieces and build a tower.
  7. 9. Complexity: This is the idea that some things are so complicated that they couldn't have been made simpler and still work. Like a mousetrap: if you take away any part, it won't catch mice.
  8. 12. This is a way to categorize living things based on how similar or different they are. Like how you might sort your music playlists into different genres.
  9. 13. Selection: This is how nature picks which traits are best for survival. If you're a fast runner in a world of slow zombies, you're more likely to survive!
  10. 16. This is the part of metabolism that breaks things down. Imagine you have a LEGO tower, and you take it apart—that's like catabolism.
