Why are humans destroying habitats?
Humans are ruining animal habitats because they need room to build houses(subdivisions), factories, and any other type of building. As much as this is not right, where else would they build all of these places? other than just livin outide idk. But all I'm sayin is jst dnt b surprised whenanimals are "overpopulating".
Economic necessity.
Greed
Lack of foresight
What is an example of cnidarians?
Cnidarians are the group of invertebrate animals which possess stinging cells called cnidocytes. The popularly-known cnidarians fall into only a couple of major groups. The Anthozoans or corals, sea pens, and anemones are sessile--that is stationary in lifestyle. The Scyphozoa or jellyfish are motile (mobile in lifestyle). So, the answer to the question is that anemones, coral, and jellyfish are all cnidarians.
What is the largest invertebrate known on Earth?
Giant squid is largest known living invertebrate animal on earth .
What bugs are good for plants?
Big-eyed (Geocoris spp) and damsel (Nabidaefamily) hemipterans are examples of bugs that are good for plants. Bugs taxonomically belong to the Hemiptera insect order and may include both beneficial and harmful members.
Yes, diatoms are autotrophs because they can photosynthesize to produce their own food using sunlight, carbon dioxide, and other nutrients. They are a type of algae that play a significant role in marine and freshwater ecosystems.
What does the sea anemone weigh?
Sea anemones are marine creatures with varying sizes and weights depending on the species. On average, sea anemones can weigh anywhere from a few ounces to a couple of pounds. Their weight can also fluctuate depending on factors such as the amount of water they absorb or release in their body.
What damage do box elder bugs cause?
Introduction of viruses, unsightly appearance, and weakening of defenses appear on the list of damages caused by box elder bugs (Boisea trivittata). The insects in question feed upon plant sap, and any time that an opening is made into a vegetative part defenses are compromised, life-sustaining activities must be re-prioritized, and viruses will be able to access vulnerable interiors.
What are the major evolutionary trends among the metazoan invertebrate phyla?
Perhaps the most significant evolutionary trend among the metazoan invertebrate phyla is that of cephalization. This term refers to the development of a head, containing a brain. Another process called segmentation allowed animals to develop distinct body parts, such as legs, wings and feelers.
Yes, aphids are harmful. The insects in question (Aphidoidea superfamily) extract internal, vital saps from edible, ornamental, and woody plants while simultaneously disfiguring foliar surfaces, reducing marketability and usability, and vectoring viral diseases.
What is a stinging cell cnidarian called?
A cnidocyte, cnidoblast, or nematocyte is a type of venomous cell unique to the phylum Cnidaria (corals, sea anemones, hydrae, jellyfish, etc.). The cnidocyte cell provides a means for them to catch prey and defend themselves from predators. A cnidocyte fires a structure that contains the toxin, from a characteristic sub-cellular organelle called a cnidocyst (also known as a cnida or nematocyst). This is responsible for the stings delivered by jellyfish.
No, cnidarians are not protostomes. They are classified as diploblastic animals, meaning they have two germ layers during development (endoderm and ectoderm), whereas protostomes are triploblastic animals with three germ layers. Cnidarians are more closely related to animals like jellyfish, corals, and sea anemones.
Are horses invertebrates or vertebrates?
They are vertebrate.
They are Vertebrates because they have a backbone invertebrates are animals that dont have a backbone i hope this helped you x
What is the reaction of planaria to pH light and different temperature conditions?
it does not like light, and therefor moves away from it.
What does it mean to be alpha pup how do you know?
In wolf packs, the alpha is, in simplest terms, the leader. With wolf pups, the alpha position isn't serious, but this is usually the point where they establish their rank in life. So, to be an alpha pup is to be a probable future leader of the pack.
The majority of mollusca species live in marine environments, and many of them are found intertidally, in the shallow subtidal and on the continental shelf.
What is the excretion of cnidaria?
it is where the the nutrients runs out of the mouth or the anus of the organism therefor they take the nutrients that other organisms leave behind and they get the nutrients from that that is the excretion of cnidaria
What is a flower-like ocean-dwelling invertebrate with stinging tentacles?
Jellyfish - which is a common group name for several species.
Well what makes them invertabrates is that they don't have back bones or spine.
