Kelps are characterized by three main parts: blades, stipes, and holdfasts. The blades are similar to the leaves of land plants. They are the photosynthetic factories of the kelp. It is here that energy from sunlight and nutrients from the water are combined to produce food.
What snails eat kelp?
Brown turban snails live on kelp plants, most often on the upper blades. Predators like the sea star live on the seafloor below, so the turban snail is safer up high in the canopy. Kelp provides lunch as well as a living-place for the turban snail. The snails rasp away the algae with their file-like tongues.
Why is algae not a plant?
The main reason is that they contain chloroplasts and produce food through photosynthesis. However, they lack many other structures of true plants. For example, algae do not have roots, stems, or leaves. Some algae also differ from plants in being motile.
Why is kelp not an animal?
Not an Animal, Not a Plant So although kelp is commonly called a plant, according to scientists, all types of kelp are actually types of eukaryotic algae. Algae are simpler than flowering plants that lack tissues to carry water and food from one part to another.

Do fleas have brains?
Insects have tiny brains inside their heads. They also have little brains known as “ganglia” spread out across their bodies. The insects can see, smell, and sense things quicker than us. Their brains help them feed and sense danger faster, which makes them incredibly hard to kill sometimes.
Do octopus have brains?
Most of the octopuses were eventually successful at guiding their arm to the food – proving that the central brain, which processed the visual information, could control the arm. Thanks to their nine brains, it seems that octopuses have the benefit of both localised and centralised control over their actions.
How many brains has a leech?
The leeches that I have driven several hundred miles to encounter are freshwater, bloodsucking, multi-segmented annelid worms with 10 stomachs, 32 brains, nine pairs of testicles, and several hundred teeth that leave a distinctive bite mark.
What is a mosquitoes iq?
The extent to which genes play a part — the level of heritability — in the trait for being attractive or not to mosquitoes was found to be at a similar level (0.83) as that associated with height (0.8) and IQ (0.5-0.8).
Do sea urchins move?
Sea urchins are sought out as food by birds, sea stars, cod, lobsters, and foxes. In the northwest, sea otters are common predators of the purple sea urchin. Humans also seek out sea urchin eggs, or roe, for food. The eggs are considered a delicacy in Asia.
Do sea urchins climb?
Yes. I have a tuxedo urchin that goes all over and leaves trails in the coralline. If your coralline grows really faster your urchin may not even put a noticeable dent in it. They will climb the glass.
Do sea urchins live together?
Sea urchins often live in clusters or in solitary settings among other types of ocean life. The habitats of these spiny creatures vary, from rocks close to shorelines to deep on the ocean floor.

Are molluscs zooplankton?
Macroscopic zooplankton include pelagic cnidarians, ctenophores, molluscs, arthropods and tunicates, as well as planktonic arrow worms and bristle worms. Zooplankton is a categorization spanning a range of organism sizes including small protozoans and large metazoans.
Are phytoplankton autotrophs?
Phytoplankton, tiny organisms that live in the ocean, are autotrophs. Some types of bacteria are autotrophs. Most autotrophs use a process called photosynthesis to make their food.
Are phytoplankton herbivores?
Are phytoplankton producers consumers or decomposers?
Phytoplankton are the tiny, plant-like producers of the plankton community. They include bacteria and algae that form the base of aquatic food webs.
