Marine Science Ch 16
Ch 16 Review MCs
| Question | Answer | |
|---|---|---|
| What is the basis for life in the hydrothermal vent community? | chemosynthesizers | |
| What is water called when it is a mixture of both freshwater and sea water? | brackish water | |
| Which distribution is the rarest found in communities? | uniform distribution | |
| What is the study of the balance between environmental factors and organisms in a community? | ecology | |
| What is arguably the best-adapted organism for the deep uniform environment of the ocean? | brittle stars (ophiuroids) | |
| What is a community? | The many populations of organisms that interact at a particular location | |
| What community has the highest biomass per unit of surface area? | estuary | |
| Where is there no deep scattering layer present? | the Artic | |
| What can occur when organisms are exposed to air and sunlight? | desiccation | |
| What describes a fish species with a narrow tolerance of temperature changes? | stenothermal | |
| What do most deep water consumers depend on for survival? | stuff coming from above | |
| What process reestablishes climax communities after a major disruption in the environment? | succession | |
| What is environmental resistance? | the sum of the effects of limiting factors in the environment | |
| Why do tropical coral reefs prefer high wave energy locations? | to be the first in obtaining dissolved and suspended material in the water; food particles | |
| What provides the raw material for large and complex food webs within an estuary? | decomposition of fast-growing, self-tolerant plants | |
| What is the name for the pelagic community that lives in the upper limits of the permanent darkness in the deep ocean? | deep scattering layer | |
| What determines the number and composition of the populations in a community? | food, light, space, and temperature | |
| What do many deep water organisms use for feeding and the attraction of mates? | bioluminescence | |
| Why was the feeding strategy of "Riftia" worms such a mystery to scientists when they were first discovered? | they had no mouth, digestive tract, or anus | |
| What is a climax community? | a stable long-established (term) community | |
| What phylum is the most successful and widely distributed in terms of parasites? | Nematoda | |
| What is the largest marine community? | the permanently dark water between the sunlit surface and the deep bottom; the deep scattering layer | |
| If an animal is tightly attached to the rocks during intense wave activity, it is said to be: | sessile | |
| Which is not a characteristic of deep water animals? | ARE: slow metabolic rate, slow movement, little consumption, and long life-span | |
| What is a hardship for small organisms that are associated with living on a sandy beach? | hard to dig, move, and hide from predators; surface is a blizzard of abrasive particles which gets into soft tissues and wears away protective shells, capillary forces pinning them down, exposure to overheating or freezing, osmotic shock from rain, | and crushing by heavy animals, separating food from sand, and crashing waves |
| What can the accumulation of coral and sediment change in the environment? | current patterns, ocean temperature, and the proportions of dissolved gases | |
| What is thought to aid the proliferation and spread of hydrothermal vents? | fallen bodies of whales | |
| How much biomass in tropical coral reefs is attributed to the coral alone? | half 1/2 0.5 | |
| What effect does wave shock have on intertidal organisms? | tearing at their structures and underpinnings | |
| What is a niche? | an occupation within a community |
