• 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.
