• When individuals of the same species hang out, work together, or even sometimes fight, it's called an intraspecific relationship.
• Imagine you and your siblings fighting over the last cookie or helping each other with chores. It's kind of like that, but in the animal and plant kingdom.

• Key Concept: When creatures of the same species need the same resource, but there's not enough to go around, they have to fight for it (compete).

  • For example: Two deer might spar over the best grazing patch.

• Outcome: Those who win these competitions (like the deer with the strongest antlers) have a better chance of surviving and making baby deer.

  • Over time, nature will favor those with the best "winning" traits. This is called natural selection.

📷 Figures 18-21: Imagine pictures here showing different animals or plants in heated competitions. Like two trees growing super close and both stretching towards the sun.

• Key Concept: Sometimes, creatures of the same species help each other out. Because teamwork makes the dream work!

  • For example: Termites work together to build massive mounds. One alone couldn't do it.

• Outcome: Cooperation often leads to benefits for everyone involved.

  • Unlike competition where everyone might get a little hurt, cooperation ensures that everyone wins!

📷 Figures 22-25: Think about cool photos of animals or plants cooperating. Like a group of ants carrying a big leaf together.
