Can someone please explain to me what a niche is? And differentiate it with a habitat (not like a huge paragraph just the main point)
So I’m stuck with this here. The Directions are to label the examples below either habitat or niche. (these are the numbers on the paper, I don’t want to get confused)
12. A chameleon changes its colors to blend in with its surroundings.
13. Ducks and amphibians live in or near a pond.
14. Birds nest in trees.
15. A male lion’s mane attracts a mate.
16. Your cat’s sense of smell helps it find its way home.
17. Monarch butterflies eat milkweed, making them poisonous to other species.
18. Woodpeckers use their beaks to pry insects from trees.
Please, somebody help me here!!

or the past two years I’ve had a robin’s nest in a small Colorado Spruce in my front yard. This winter I noticed that there had been two nests all along, one around two feet above the other. I have always seen the Robins guarding the tree from march until migration time, even until now. But today I have been watching a mourning dove flying debris it has collected from my yard in and flying out the tree. The Robin standing on the ground near by, watching. I would rather have robins for pest control reasons. Is it possible they can nest so close with each other?
-I am having a hard time finding the perfect category for this question.
