7. What are some advantages to size and area and what are the tradeoffs?
Advantages to size and area: with larger leave it can produce more energy
for photosynthesis , the tradeoff is water loss
8. What is the stomata used for and why does water loss occu
What affects the rate of gas diffusion?
Partial pressure , think partial pressure at sea level vs
on a mountain.
2. What is the biggest advantage to living on land?
Oxygen is plentiful
3.Why is that an advantage?
Because our human lungs work in this envir
15. What are some adaptations marine organisms have for water
They need less buoyancy
16. What are some adaptations freshwater organisms have for
They need more buoyancy. So a swim bladder in fish is more
important since smaller or
11. What are some problems in with saltwater concentrations in freshwater
Too much water
Loss of salt
12.What are some adaptations fish have evolved for salt concentration in
They have evolved a more rigid body that is not permeab
6.What are some estuary adaptations?
Some plants like the salt grass will excrete excess salt , others like pickle weed sequesters the
salt. Some organisms move away as the salinity changes
7. Describe the bill length vs prey depth,
As clams go deeper to
What is the difference between an estuary and slough?
An estuary has a direct input of water
A slough does not have a large influx of water, it is controlled by tidel action, no continual input
2. Define a flood tide
That is when seawater comes int
To counteract the density of the water marine organisms have adapted ways to maintain their buoyancy
in the ocean.
Some animals have gas bladders
A jellyfish has one in order to stay near the surface, where its food source is located.
What are some challenges in the deep ocean? And adaptations?
There is a lack of light
This make it difficult to locate prey
The adaptation to this is large eyes. Adaptations in sensory organs help them see
Bioluminescence helps attract prey (fi
What are some physical characteristics of the ocean?
The ocean is a liquid medium that is dense (1000x more than air). This affects body
shapes,ability to breathe underwater, there is more pressure on the animal bc all water is just
sitting on the animal.
