Answer:
Climate change is the change of temperature in the worlds climate system and climate variability is the variations in a certain climate that last longer then certain weather events.
Explanation:
To explain more climate change is the change in the daily weather in a area for example rain forest to desert or cold to hot climate change goes along with global warming which is the heating of our Earth which causes ice to melt in the arctic rising our sea levels creating stronger storms. While in a climate variability its only a certain time of that specific climate change for example its only cold for a certain period of time then the temperature rises to hot again. So, the key difference is that "climate change is the change of temperature in the worlds climate system and climate variability is the variations in a certain climate that last longer then certain weather events."
Hope this helps!
The sun is a vital part of the earth, so if it changes energy levels, it will clearly have an affect on the earth. If the energy increases, it'll most likely dry out the grass and melt the snow, etc. If it decreases, the snow could freeze and change the climate.
Answer:
A limiating factor is what limits the poupulation in an ecosystem. For example, biotic limiting factors include food, mates, shelter. Without these things the poupulation would decrease. becuse food, mates, and shelter are limited it limits the poupulation. an example of an abiotic limiting factor is a predetor. Predetors limit the poupulation of there pray.
Explanation:
Answer:The correct answer is chordates
Explanation:
Organism in the phylum Chordata develop dorsal nerve cord in their embryonic stage. Development of dorsal nerve cord is the characteristic feature of these animals and is developed by the mesoderm layer. In many of them they are only present in embryonic stage.
In vertebrates notocord disappears after completion of embryonic stage and is replaced by vertebral column which provide support and anchor to the body structure of vertebrates.
Tunicates are chordates and have dorsal nerve cord only in prenatal stage and it disappears in adults.
Answer:
Cost: competition for mates, competition for resources
Benefit: better protection from predators (ex. a fish in a school of fish has greater chances of not getting eaten because of the large number of other fish)
