Life Sciences Graphic Organizer Bundle. Graphic Organizers have done wonders in my classroom, especially with science concepts. Here are 6 of my life science organizers that will help your students gain a better understanding of these concepts: This graphic organizer will allow your students to better understand how animals adapt to their environments.
Included are three version to help with differentiation. The first version is color coded to help with memorization and includes the type of Adaption. Your students will be required to complete the definition and give an animal for example. The second version has only has arrows that are color coded and also includes the type of adaption. The third version is color coded but not include the adaption. Add one to cart. The monarch butterfly shown on the left and the viceroy butterfly shown on the right will make animals sick or taste very bad if they are eaten.
When two unpalatable species resemble each other, they reinforce avoidance by predators by increasing the frequency of unfavorable encounters. The predators learn faster, and fewer butterflies of both species are eaten during the learning process.
Cheetahs use speed to outrun their prey, and eagles, hawks, owls and falcons use flight to their advantage while hunting. Venomous snakes, spiders and wasps use poisons to either kill or immobilize their prey. Some predators even use mimicry to capture prey. The alligator snapping turtle uses its pink worm-like tongue as a lure to draw fish right into its mouth. The turtle will sit submerged underwater with its mouth wide open and flail its tongue around like a writhing worm.
When an unsuspecting fish goes after the tongue, the turtle snaps its mouth shut and eats the fish instead. Get FREE access for 5 days, just create an account. When it all comes down to it, predators and prey are in a constant battle to gain an advantage that will help them survive.
Whenever a predator develops an advantage that helps them acquire prey, there is selective pressure on the prey to adapt and find a way to avoid this new method of predation. The organisms that most effectively adapt to and avoid predation will survive and reproduce. It works in the opposite direction too. When prey organisms develop an effective defense against predation, predators must adapt to the change and find a way around the defense, or find a new organism to prey on.
The end result is that predators and prey evolve in response to interactions with each other. These tight evolutionary relationships can result in coevolution , which is when two species evolve in a coordinated fashion by adapting to changes in each other.
A good example of coevolution occurring between an herbivore and a plant is the coevolution of the Heliconius butterfly and passionflower vines. Passionflower vines contain toxic compounds in their leaves that make them inedible to most herbivores.
However, Heliconius larvae have evolved enzymes that break down the toxic compounds and allow them to eat the leaves of the vines. Heliconius butterflies lay their bright yellow eggs on the passionflower leaves because they are a good food source for the larvae.
Amazingly, some species of passionflower vines have bright yellow structures on their leaves that look like Heliconius eggs. These structures deter the butterflies from laying their eggs there, and more than that, these structures are actually nectaries that provide food for ants and other predatory insects that eat Heliconius eggs and larvae.
So the yellow structure defense is two-fold: It deters the butterflies from laying eggs, and it attracts predators of Heliconius larvae.
These back-and-forth counter-adaptations are what cause coevolution between predators and prey. A predator is an animal that hunts and kills other animals for food. While some animals rely on camouflage, others, especially those with chemical deterrents, have bright or distinctive markings that serve as a warning to would-be predators called warning coloration. Some harmless animals take advantage of warning coloration and mimic other brightly colored species. There are also cases where two or more dangerous or unpalatable species all resemble one another.
The end result of all of these interactions is that predators and prey evolve in response to interactions with each other. These tight evolutionary relationships can result in coevolution , when two species evolve in a coordinated fashion by adapting to changes in each other. To unlock this lesson you must be a Study.
