There are two different food chains in this example: 1. Spinach --> goat --> human --> tiger
2. Spinach --> goat --> tiger
Analyze whether the tiger is at the same level and whether it obtains the same amount of energy in both the food chains.
A.
In the first food chain, tiger stands at a secondary consumer level whereas in the second food chain, it stands at primary consumer level; hence energy obtained in the second food chain is more than in the first.
B.
In the first food chain, tiger stands at a tertiary consumer level whereas in the second food chain, it stands at secondary consumer level; hence energy obtained in the second food chain is more than in the first.
C.
In both the food chains, tiger stands at a tertiary consumer level, because tiger is always a tertiary consumer; hence it obtains same amount of energy in both food chains.

Based on their location in the atmosphere, the layers are able to have their own special characteristics. for example, most weather occurs in the troposphere. what occurs in each of the other layers? (site 1)

Nhumans, abo blood types refer to glycoproteins in the membranes of red blood cells. there are three alleles for this autosomal gene: ia, ib, and i. the ia allele codes for the a glycoprotein, the ib allele codes for the b glycoprotein, and the i allele doesn't code for any membrane glycoprotein. ia and ib are codominant, and i is recessive to both ia and ib. people with type a blood have the genotypes iaia or iai, people with type b blood are ibib or ibi, people with type ab blood are iaib, and people with type o blood are ii. if a woman with type ab blood marries a man with type o blood, which of the following blood types could their children possibly have? in humans, abo blood types refer to glycoproteins in the membranes of red blood cells. there are three alleles for this autosomal gene: ia, ib, and i. the ia allele codes for the a glycoprotein, the ib allele codes for the b glycoprotein, and the i allele doesn't code for any membrane glycoprotein. ia and ib are codominant, and i is recessive to both ia and ib. people with type a blood have the genotypes iaia or iai, people with type b blood are ibib or ibi, people with type ab blood are iaib, and people with type o blood are ii. if a woman with type ab blood marries a man with type o blood, which of the following blood types could their children possibly have? a, b, ab, and o ab and o a, b, and o a and b
