Honesty - Integrity Pledge
Cheating is insidious - it convinces us that "it isn't a big deal this one time", or "everyone else is doing it", or "this isn't an important thing I am cheating on", until it is EVERY time and you ARE the only one cheating and it IS on the important things. To paraphrase the esteemed Vanderbilt Professor Madison Sarratt - "Today I will be giving you two tests, one is in Science and the other is a much more real test: one of your integrity. I sincerely hope you will pass both, but if you must fail one test, then I hope it will be the Science test, for there are many good people in the world who couldn’t pass a test in Science, but there are no good people in the world who couldn’t pass a test of their integrity.” – Mrs. Maser

The Pantanal wetlands expand across western Brazil, Bolivia, and Paraguay. During the rainy season, almost all of the Pantanal is underwater. The water moves slowly through the dense plants that grow throughout the wetlands.
The Pantanal is home to the capybara, the largest rodent species in the world. Capybaras spend so much time in the water that they are considered semiaquatic. Their partially webbed toes help them to swim. Capybaras eat water plants such as the water hyacinth.
In the Pantanal wetlands, the capybaras make up which of the following? Select all that apply.

Strangler figs are part of many symbiotic relationships in a rain-forest ecosystem. In some cases, the symbiotic relationship benefits both the fig and an animal. Fig wasps lay their eggs in the fruit of the strangler fig and, in turn, pollinate it. Many birds feed on the fruit of the strangler fig and, in doing so, spread the seeds of the plant. The fig does not benefit from its interactions with all species. For example, certain butterflies feed on juice from the fruit without affecting the tree in any way.

The symbiotic relationship that gives the strangler fig its name is that between the strangler fig and its host tree. Birds drop seeds onto the top of a tree, and vines of the fig grow downward. Eventually, the vines of the strangler fig touch the ground and join with the roots of the host tree. The host tree is harmed because the leaves of the strangler fig block sunlight and its vines take root, using up nutrients the host tree needs.

Write a paragraph describing some of the different roles played by a strangler fig in the rain forest. Use the vocabulary words - habitat, niche, populations, community and ecosystem.
