Invertebrates

When diatoms die, their shells are called frustules. These microscopic structures are made of silica and can accumulate in large numbers on the ocean floor, forming sediment known as diatomaceous earth.

Mollusks have a mantle, which is a thin layer of tissue that covers their body and secretes the shell in shelled mollusks. The mantle plays a key role in respiration, excretion, and shell formation in mollusks.

Many aquatic organisms consume diatoms. Diatoms are an important type of primary producer in marine and freshwater systems and are a type of algae. In marine systems, many zooplankton and some small fish consume diatoms.

Diatoms are microscopic algae that are not typically consumed by humans as a direct food source. However, some marine organisms such as certain species of zooplankton and small fish do consume diatoms as part of their diet.

zooflagellates are more animal-like flagellates (eg, triconympha that live in the digestive tract of termites), and dinoflagellates are more plant-like flagellates (phytoflagellates) - Autotrophic organisms.

the ground-up diatoms are added to cleansers because they are hard and don't scratch any surface.

Yes, anemones are carnivorous animals. They capture their prey using their stinging tentacles and then consume them by pushing the prey into their mouth located at the center of their body. Their diet typically consists of small fish, crustaceans, and plankton.

The fastest invertebrate is the common squid, which can reach speeds of up to 25 miles per hour (40 kilometers per hour). This remarkable speed is achieved through jet propulsion, where the squid expels water from its funnel to propel itself forward rapidly.

The basic purpose of internal skeleton is to provide place for attachment of muscles. The internal skeleton protects the essential organs like heart and lungs (rib cage). The backbone gives flexibility to move. The girdles support the limbs. The skull protects our brain. All evolved in course of time to meet the demands of animal encounter with the environmental conditions.

Both predator and prey as with most animals in this world.

fast running rivers! there so many leeches there!

An overfishing of herring can disrupt the food chain and remove a key predator of sea urchins. With fewer herring to feed on sea urchins, their populations can increase unchecked leading to ecosystem imbalance and potentially to overgrazing on kelp forests where sea urchins feed.

Cnidarians first paralyze their prey with stinging cells on their tentacles then they slowly move the food up into the bell to digest . They have no distinct mouth or anus so the food goes in and out around the same place.

We had a huge flea problem upon moving into our house, I guess the old owner had some issues. We found out that Diatomaceous Earth (DE) worked great for getting rid of them and was nontoxic. We got a couple of masks and cleared out the house so that the powder was not breathed on by any one, when you spread it the powder is so fine that a dust fills the and while it is non toxic you don't want to breath it in because it will irritate your nose, throat and lungs. I also recommend some goggles.
After I spread it on I used the vacuum with the hose disconnected to 'beat' the powder deeper into the carpet. Then I let it sit for a while and vacuumed lightly. It worked great! I applied it twice, the second time a week later just to be sure.
Make sure you do some research before this just to be on the safe side. I would also try to vacate the area for a while after laying it down and after vacuuming. Also, use an old vacuum if you can as the powder is so fine it clogs the vacuum really easy.
This was not an easy task but with a little effort it definitely beats having to deal with fumes and residue, although I would recommend covering anything electronic and doing a thorough cleaning afterward. Hope this helps!

Most primary producers, such as plants, algae, and some bacteria, use photosynthesis to make their own food. They use sunlight, carbon dioxide, and water to produce glucose (sugar) and oxygen. Some primary producers, like certain bacteria, can also use chemosynthesis where they acquire energy from chemical reactions to make food.

In an earthworm, nephridia occur in all body segments except the first three segments. Integumentary nephridia are V-shaped and lack nephrostomes.

Insects are diverse in the animal kingdom I believe for several reasons.

1. Insects typically have a short life cycle, and so they go through many generations in a short period of time. This allows fow an increased rate of mutation.

2. Insects are low on the food chain, and so have developed many diverse survival strategies for dealing with predation.

3. Insects have been on the earth longer than most other animals, ( like reptiles, mammals birds etc.) and so have had the time to obtain a greater amount of diversity.

4. Insects are typically biologically simpler organisms than other animals, and so they are easier for ol' mother nature to make (so to speak).

5. Insects are small, and so each individual uses fewer resources than a larger animal. This allows for a greater population density in any given natural area. A bigger population usually means a greater amount of genetic diversity.

I'm no entomologist but I think those are some good reasons to start out with.

The scientific name of Diatom is Bacillariophyceae. Diatoms are unicellular algae that appears as colony shaped like filaments or ribbons, fans, zigzags, or stars.

Snails and slugs are a smaller group of invertebrates known as gastropods. They have a soft body, usually protected by a shell, and move by producing mucus to glide along surfaces. The majority of gastropods are marine, but some are also found in freshwater and terrestrial habitats.

No, diatoms are not vascular plants. Diatoms are a type of single-celled algae that possess a cell wall made of silica, while vascular plants are higher plants that have specialized tissues to transport water, nutrients, and produce seeds for reproduction.

Tree hoppers play a role in the ecosystem by feeding on plant sap and helping to regulate plant populations. They can also serve as a food source for other animals, helping to maintain biodiversity. However, in large numbers, tree hoppers can damage plants by sucking out too much sap, which can weaken or kill the plant.

Diatoms are a major group of eukaryotic algae, and are one of the most common types of phytoplankton. Diatoms occur in virtually every environment that contains water. This includes not only oceans, seas, lakes and streams, but also soil.

Diatoms, slime molds, and green algae are types of protists. Protists are a diverse group of eukaryotic organisms that are not plants, animals, or fungi. They can be found in various habitats, from freshwater to marine environments.

The arachnids group has a body that is divided into a cephalothorax and an abdomen. This group includes spiders, scorpions, ticks, mites, and more.

Im up it the part where i need the sea urchins for tobors scrool . and ive been looking every where and I think you can get them by fishing in either rocket reef or the nature perserve. if not just wait till you get to the other islaands!
