No, the tiger is not at the same level in the food chain.
Explanation:
There are two different food chains in this example: 1. Spinach --> goat --> human --> tiger 2. Spinach --> goat --> tiger.
In the first example, tiger is a tertiary consumer because it feed on secondary consumer that is human which feeds on primary consumer, while in the second example, the tiger is secondary consumer because it feeds on primary consumer that is goat which feeds on producer. In the food chain, there are different trophic levels are present such as producer, primary consumer, secondary consumer and tertiary consumer etc. Some animals act as both secondary and tertiary consumer. In these two examples, tiger act as both secondary and tertiary consumer.
Answer:
D
Explanation:
Every organism, even the almighty elephant, starts as a single cell. This single cell continually divides mitotically to form the adult organism. Contained in this single cell, is a DNA, coding for all proteins the adult organism will use. All these proteins will not be expressed at once, rather the cells keep dividing and as they divide they undergo gene expression to become specific types of cells. This process is called CELL DIFFERENTIATION.
Cell differentiation is the process by which dividing cells change their function or phenotypic type. Eventually, an organism with hundreds of different types of cells is formed by this process of cell differentiation.
After fertilization in animals (scorpion inclusive), a single celled zygote is formed. This zygote is totipotent i.e. capable of repeated division to form differentiated cells The cells of zygote then undergoes division and during the division, it becomes differentiated to form complex tissues and organs which make up the its body parts including its stinging tail. All cells emanate from the stem cells and becomes specialized as they mature.
N.B: the original mass of cells yet to undergo differentiation are known as STEM CELLS and they are contained in the zygote.
