Evolutionary Tree / Sorting Activity Create your own tree-branching model to organize the beetles based on ages and similarities in structures.
You can do this activity in different ways - depending on your resources and what helps you understand:
1. If you have a printer, you could print this document and cut out and arrange the beetles.
2. If you don't have a printer, write the letters on a piece of paper, cut them out and arrange them.
3. Or, just write the letters on a piece of paper in an organized tree-branching model.
A, B and C are modern-day beetles, while the others are fossils. The numbers in parentheses tell how many
millions of years old the fossils are, based on absolute dating.

That is true tge cactus as a structural adaptation to its envirinment has it leaves reduced to spines. but this doesnt mean it cant produce food it produces food because of the presence of chlorophyll in its stem

Hunting in the darksome fish rely on senses beyond sight. in the darkness of the marianas trench, a fish called the rattail has an extremely sensitive sense of smell. the fish uses scent, rather than sight, to steer toward food. once it's near food, the rattail uses a special organ on the bottom of its chin to guide itself by feel.marine snowone staple of the deep sea diet is "marine snow," flakes of organic, edible substances that sink down from the upper ocean. animals at the ocean's bottom find sustenance in everything from the bodies of dead creatures to fecal matter. marine snow is diverse enough to support numerous species. for instance, several species of snails and worms feed exclusively on deceased whales.microorganismsthe deep sea is an intricate ecosystem, and even the ocean floor itself plays a part. hydrothermal vents are cracks in the sea floor where erupting magma mixes with ocean water to produce plumes of hot, sulfur-rich chemicals. some microbes can use these chemicals for energy, sustaining their existence and that of the animals who depend on their roles in the deep sea food chain.
