Two species belonging to the same class must also belong to the same?

Phylum. Organisms in the same class belong to the same phylum, which is a higher taxonomic rank that groups organisms based on shared characteristics.


Organisms that below to the same class must belong to what?

Organisms that belong to the same class must also belong to the same phylum. Classes are subdivisions of phyla in the classification hierarchy of organisms.


If humans and pandas belong to the same class then they must also belong to the same?

Phylum (Chordata), as class is located at a lower taxonomic level than phylum for classification of organisms.


Does organisms must be compete with each other for space to live in?

It depends on the organisms and their habitats. Most of the time, yes, organisms must compete, as this space also contains items necessary for survival such as food and water.


What kingdom contains multicellular organisms that do not make their own food?

The kingdom Animalia contains multicellular organisms that do not make their own food. These organisms are heterotrophic, meaning they must consume other organisms for energy.


Organisms that belong to the same class must belong to the same?

Phylum. Organisms in the same class share similar characteristics and evolutionary traits that place them within a specific group. These groups are then further classified into phyla based on broader similarities.


Is cockroach a mammals?

No. To be considered a mammal, an organism must be in the Class Mammalia. Cockroaches are not even in the same Phylum as Mammals. They are in the Phylum Arthropod and Mammals are in the Phylum Chordata.


Do snails go through photosynthesis?

No, snails do not go through photosynthesis. Photosynthesis is a process unique to plants and some bacteria, where sunlight is converted into energy. Snails are heterotrophic organisms that obtain their energy by consuming other organisms or organic matter.


What must happen first for sponges to evolve?

the evolution of cells with nuclei and organelles


Organisms that must feed on other organisms for energy are known as?

Consumers ^_^


What must form first for a cast to be made?

📷 Organisms buried in sediment slowly decompose, leaving a cavity that contains an exact imprint of the organisms' shape and size. When this hollow space fills with material, this material takes the shape of the mold, forming a cast.


Are elephants chordates?

The phylum Chordata contains all animals that possess, at some point during their lives, a hollow nerve cord and a notochord, a flexible rod between the nerve cord and the digestive track. The phylum Chordata is an extremely diverse phylum, and the one most recognizable to us. The phylum contains about 43,700 species, most of them concentrated in the subphylum Vertebrata, making it the third-largest phylum in the animal kingdom. The phylum Chordata is divided into three subphylums: Urochordata (tunicates), Cephalachordata (lancelets), and Vertebrata (vertebrates). The first two phyla are very small containing only about 2,000 species total. Tunicates are marine animals that only show the attributes of the chordata phylum in the larva stage, and when they turn into adults lose the notochord and nerve cord. Adult tunicates look like small sacs around 3 cm tall attached to the ocean floor. Lancelets, which are similar in appearance to small fish, keep the nerve chord and notochord into maturity but are extremely simple in structure and lack a backbone. The third phylum, vertebrata, is the most important, and is distinguished by a backbone (made either of bone or cartilage) containing interlocking vertebrae and a skull enclosing a brain. These two features serve to protect the entire central nervous system, and in addition give support and structure to the body; these bones also form part of a larger system of bones, the endoskeletal system. Unlike the exoskeleton of other phylums such as the arthropods, which must be shed periodically, this endoskeleton is permanent and can grow with the organism. This endoskeleton gives vertebrates a competitive edge over all other animals, as it can easily be scaled for use in large organisms, and it allows these organisms to be relatively light and fast-moving. In comparison, most organisms with an exoskeleton are small and slow-moving, due to the limitations of their large and bulky skeletal system.
