SPACE TO GROW
In the animal kingdom, the male of the species is usually “better looking”
than the female of the species.
Look at these lions.
Do you know which one is the male?
than the female in the species?
If you said it is help them when they want to attract a mate….then you are correct.
Which peacock do you think is the male?
The reason that the female Cardinal is less colorful than the male is because she is the one that protects the nest. If her color was bright, it might attract the attention of a predator.
Do you know why the female’s coloring is less attractive?
It is because she is the one that does the hunting for the pride. Her coloring needs to be able to “blend in” with her surroundings so that her prey will not see her before she attacks.
Look at this cactus.
The leaves of a cactus are the spines like you can see in this picture.
Why would a cactus need small, thin leaves?
In the desert, the sun shines almost everyday.
The leaves of the cactus are small because they don’t have to work hard to absorb sunshine to make its food, because the sun shines so much of the time.
Remember that the leaves release water thrrough transpiration…and in the desert, the plants want to hold on to as much water as possible.
smaller leaves = less transpiration
In this environment, the leaves in the lowest level of the rainforest need big leaves so that they can capture any sunshine that makes its way through the taller trees that tend to block the sunlight.
Can you think of ways that
adapt to your environment?
