Question

1.Please read about these biotic interactions in your textbook. Then please show which species benefits (by drawing a + in the correct row) or incurs costs (indicate with a ) from each of these interactions. (4 pts) Species 1 Species 2 interaction predation (both carnivory & herbivory) parasitism mutualism competition 2. Scientific writing differs from other forms of writing in that scientific wrfting must be concise, clear, & complete (the 3 C's). Remember that hypotheses must be testable, tentative, logical explanations of observations. Please examine the 2 images of multicellular organisms (I hope that you won't recognize them, & you're on your academic honor to avoid trying to identify them!). Based on your observations, please write a hypothesis about the ecology of one of these life forms (no hypotheses about its identity). You'll have to indicate either A or B! Your hypothesis: images are not to scale) (5 pts) B! (marine habitat) &

Answer 1

In predation, one species benefits (predator, carnivore -tiger,herbivore-deer)while the other species (prey,carnivore -deer,herbivore-grass) incurs costs.

Species & Interaction Species I Predation Parasitism Mutualism Competition

In parasitism, one species benefits (parasite, example -liver fluke) while the other species incurs costs (human).

Both the species benefit in Mutualism. Example -fig species can be pollinated by wasp species. Female wasp uses the fruit of fig for oviposition and also uses developing seed for nourishing its larvae. And in return the wasp pollinates the fig inflorescence.

In competition, both the interacting species incurs costs (lose).
