Responses
When two organisms compete for shelter, the strongest will win.

Organisms that survive to reproduction are well adapted to their environment.

Environmental changes do not influence species' survival.
Environmental changes can influence species' survival, but the ones that are most well adapted to the changes are more likely to survive and reproduce.
A student observed a graduated cylinder with a volume of 600mL. After placing a large rock in the graduated cylinder the student observed a volume of 740mL. What is the volume of the large rock?

740mL
The volume of the large rock is 140mL.
Explanation:
The initial volume of the graduated cylinder was 600mL. After adding the rock, the volume increased to 740mL. Therefore, the volume of the rock is the difference between the final volume (740mL) and the initial volume (600mL):
Volume of rock = final volume - initial volume
Volume of rock = 740mL - 600mL
Volume of rock = 140mL
The term "survival of the fittest" refers to the concept in evolutionary biology that individuals who are the most fit for their environment are more likely to survive and reproduce. This term was coined by Herbert Spencer, but it is associated with the work of Charles Darwin and his theory of natural selection.
When two organisms compete for resources or shelter, such as food or a nesting site, the one that is stronger or better suited to those conditions is more likely to be successful. This competition can lead to the weaker or less adapted individual being excluded or dying off, while the stronger individual survives and passes on its genes to the next generation.
It is important to note that fitness in this context refers to an organism's ability to survive and reproduce, not necessarily physical strength or dominance. Fitness can be influenced by various factors, such as adaptations, genetic traits, and behavior that increase an organism's chances of survival and reproductive success.
In addition, the process of natural selection can lead to species becoming better adapted to their environment over time. Those individuals with beneficial traits or variations that give them a competitive advantage are more likely to survive and pass those traits on to their offspring. This gradual accumulation of advantageous traits over many generations can result in the evolution of new species.
On the other hand, environmental changes or shifts in conditions can also affect the survival and extinction of species. If a species is not able to adapt quickly enough to a new environment or if its adaptations are no longer advantageous, it may become extinct. Environmental factors and selective pressures play a significant role in determining which species will survive and which ones will not.
In summary, the term "survival of the fittest" refers to the idea that individuals who are best adapted to their environment are more likely to survive and reproduce. This concept is a key component of the theory of natural selection and the process of evolution.
