Are organisms in the same class in the same phylum?
Are organisms in the same class in the same phylum?
Since the system is hierarchical, organisms belonging to the same class also belong to the same phylum and kingdom. For instance, all animals belonging to the class Reptilia (reptiles, then) also belong to the phylum Chordata (animals with a notochord, or backbone) and the kingdom Animalia (animals).
What are two organisms that belong to the same phylum?
-The broadest classifications are by domain and kingdom; the most specific classification is by genus and species. Therefore; if two organisms are in the same phylum, then it means they both belong to the same kingdom, because kingdom is the rank of classification higher than phylum.
Can two organisms belong to the same genus but not the same kingdom?
for example : if two organisms are in the same ORDER, they must be in the same class, phylum & kingdom. even though the cat & the housefly have the same species group name (domestica), they CAN’T BE the same species because they are not in the same genus, family, order, etc.
Would two animals in the same family have to be in the same genus?
If two animals are the same genus, then they must also be the same family, order, class, phylum and kingdom.
What does it mean when two species have the same genus?
In biology, hybrid has two meanings. The first meaning is the result of interbreeding between two animals or plants of different taxa. Hybrids between different species within the same genus are sometimes known as interspecific hybrids or crosses.
Which organisms develop first?
Bacteria have been the very first organisms to live on Earth. They made their appearance 3 billion years ago in the waters of the first oceans. At first, there were only anaerobic heterotrophic bacteria (the primordial atmosphere was virtually oxygen-free).
What are called the remains of living organisms?
The remains of living organisms that have been trapped in the earth’s crust are fossils. Fossils can include the petrification of living tissue including, bones, shells, carbon.
What are the first photosynthetic organisms that grow well on earth?
Timeline of Photosynthesis on Earth
4.6 billion years ago | Earth forms |
---|---|
3.4 billion years ago | First photosynthetic bacteria appear |
2.7 billion years ago | Cyanobacteria become the first oxygen producers |
2.4 – 2.3 billion years ago | Earliest evidence (from rocks) that oxygen was in the atmosphere |
Why do you think the emergence of plants and animals came later than simple living organisms?
Why do you think the emergence of plants and animals came later than simple living organisms? They contain more nucleus compared to lower forms of organisms.
How did the first living organism appear?
What are the origins of life on Earth? The first living things on Earth, single-celled micro-organisms or microbes lacking a cell nucleus or cell membrane known as prokaryotes, seem to have first appeared on Earth almost four billion years ago, just a few hundred million years after the formation of the Earth itself.
