The biotic factors can be defined as those living elements of an ecosystem that affects the other members of the ecosystem and also shapes it. The examples include animals and plants. The abiotic factors can be defined as those elements which are non-living and have effect on the other components of the ecosystem. The examples include water, air, soil etc.
A rabbit having long ears in order to disperse heat is adapting to the abiotic factor, i.e. the heat.
The spines of cactus are an adaptation to another abiotic factor, water.
The bright red color of the petunia is to attract the hummingbirds for pollination. They are adapting to the biotic factor (hummingbird).
The blending ability of stick-bugs to hide in the trees is an adaptation to the biotic factor (predators).
The diving ability of the moth is an adaptation to the biotic factor bat, in order to escape predation.
The adaptation of the lizard to sun itself on the rock in order to stay warm is in response to an abiotic factor (heat).

Answer:
<em>To reject such a null hypothesis, </em><u><em>at least one</em></u><em> </em><em>of the treatment mean must be different from the other treatment means. </em>
Explanation:
In the ANOVA, there are two possible hypotheses:
- The null hypothesis, H₀: μ₁=μ₂=μ₃=μₙ. It states that all treatment means are equal to each other.
- The alternative hypothesis, H₁ states that at least one of the treatments means is different.
When the p-value of the ANOVA test is inferior to the alfa-level of signification chosen for the analysis, then we can reject the null hypothesis. This means that there is <u>at least one</u> mean of the groups under study that is different from the rest.
<em>We can get all the means values different from each other, or just some of them. But </em><em>having only one different mean value is enough to reject the null hypothesis</em><em>. </em>
