The food chain is a system in which food is connected with the ecosystem. Ex:composers, producers, decomposers,etc.
A cactus can survive in really dry, hot weather. They store water in their "trunk." Just think of where a cuctus lives. They live in a desert. A desert is dry, hot, and lots of sun. Cactus manage to survive in that enviroment.

Answer:
Parental genotypes: RrBb, RRBB
Offspring phenotype: Running and black hair
Explanation:
Given, Running (R) is dominant over waltzing (r)
Black hair (B) is dominant over brown hair (b)
Parent 1: Heterozygous running, heterozygous black = RrBb
Parent 2: Homozygous running, homozygous black = RRBB
When they mate ( RrBb X RRBB ) :
Gametes produced by RrBb = RB, Rb, rB, rb
Gametes produced by RRBB = RB
Offspring:
RB Rb rB rb
RB RRBB RRBb RrBB RrBb
All offspring mice will be running mice and will have black hair because all the four types of genotype at least have one dominant allele for both the genes.
