Answers:1. The correct word is "phyla," not "phylums." 2. You need to do your own homework. I would be happy to help with specific questions, but not an entire homework assignment.

Answers:There's the one Phylum - Chordata - notochord present at some time disappearing early in many forms, either temporary or permanent paired gill slits; dorsal nerve cord. The Vertebrates are one of four subphylums under Chordata. There are seven Classes that make up the vertebrate part of the subphylum Cyclostomata ( example: lamprey eel - no true jaws, scales or fins) Chondrichthyes (Examples-sharks, rays) Osteichthyes ( bony fishes ) Amphibia Reptilia Aves Mammalia
Answers:> Few questions about the Phylum Mollusca? One of my favorite things. They don't fly! > Warm or cold blooded? Cold > Respiratory system type of organs does it change during lifetime? Hmmm. The general answer is no. But for some marine snails which have a larval stage, yes. > What habitat can you find this group in? Most, LOL. You'll find them in pretty much all marine and permanent aquatic environments. You'll find them in terrestrial environments where there's moisture, or moist places. > Do they migrate? I can't think of any that migrate. > Are they territorial? Most aren't. Some of the octopus species are. Some of the cuttlefish are territorial around breeding time. > How do they obtain food? Most bivalves are filter feeders. Most gastropods crawl around, and rasp food from surfaces with the radula -- you'll find detrivores, herbivores, and even carnivores doing this in this group. Cephalopods actively hunt and swim after prey. > Give an example of a food chain including these animals. Marine phytoplankton -> zooplankton -> clam Marine phytoplankton -> zooplankton -> small fish -> squid -> large fish Lettuce -> snail -> human being === > What type of reproduction is representative of this group? Sexual reproduction. Bivalves: external fertilization, eggs. Gastropods: internal fertilization. Some gastropods lay eggs, and others give live birth. Cephalopods: internal fertilization, lay eggs. > How many young at a time usually? Bivalves: thousands. Gastropods: the ones that lay eggs will lay somewhere between a dozen and a couple hundred at a time. The ones that give live birth have one at a time. Cephalopods: hundreds. > How often do they reproduce in a year? Bivalves: Hm, I don't know. Total guess: they reproduce about 26 times a year, timed by the tides. Gastropods: The ones that lay eggs will do so whenever they have some to lay. If the weather is good, every couple of weeks, I'd guess. The ones that give live birth will do so continuously in good conditions -- the adult Malaysian trumpet snails in my aquarium would give birth each and every day. Cephalopods: Once a year, I think.
