1. a coral snake is venomous while its mimic, the scarlet king snake, is not. this is an example of

a. müllerian mimicry
b. chemical mimicry
c. malthusian mimicry
d. batesian mimicry

1. the viceroy butterfly and the monarch butterfly look very similar. both are distasteful to predators. this is an example of

a. müllerian mimicry
b. chemical mimicry
c. malthusian mimicry
d. batesian mimicry

Explanation:

1. Rain is part of the hydrosphere and soil is part of the geosphere. When rain carries soil into a pond, it's an interaction between the hydrosphere and geosphere.
2. The unique role a species plays in its environment is its niche.
3. A group of many species in one place is called a community.
4. Producers form the base of the energy - pyramid and usually have the highest number of organisms as they capture energy directly from the sun.
5. Scavengers are consumers that feed on dead animals, while decomposers break down plants and animals into simpler molecules.
6. The first law of thermodynamics states that energy cannot be created or destroyed, only transferred or transformed, which explains how energy from the sun is transferred into an organism.
7. A coral snake (venomous) and its non - venomous mimic, the scarlet king snake, is an example of Batesian mimicry where a harmless species mimics a harmful one.
8. The viceroy butterfly and the monarch butterfly, both distasteful to predators, is an example of Müllerian mimicry where two or more unpalatable species resemble each other.

Answer:

1. c. Geosphere & Hydrosphere
2. b. niche
3. b. a community
4. a. Producers
5. b. scavengers; decomposers
6. a. the first law of thermodynamics
7. d. Batesian mimicry
8. a. Müllerian mimicry
