Answer:
Sun
Sun is the main source of energy on earth. About 40% light reach to the atmosphere some of which is filtered by ozone layers, water vapours and other gases. only 1% light is used in photosynthesis.
Photosynthesis
Producers contain chloroplast filled with chlorophyll molecules. when sunlight falls on leaves process of photosynthesis occurs which convert light energy into chemical energy in the form of glucose.
Respiration
Respiration occurs both in producers and consumers. in this process chemical energy (glucose) is converted into ATP, NADH and FADH2.
Decomposition
there are some organisms known as decompose s. they decompose dead bodies of plants and animals and convert complex molecules into simple nutrients with help of energy. in this way sun light energy is transferring in ecosystem in different forms.

False
Explanation:
Gregor Mendel, who was referred to as the FATHER OF GENETICS, discovered the principles that governs heredity. One of those principles which he called LAW OF INDEPENDENT ASSORTMENT states that the alleles of a gene randomly segregates into gametes independently of the alleles of another gene. This means that during gamete formation (meiosis), the separation of the alleles of one gene doesn't affect the separation of the alleles of another gene.
Mendel discovered this principle when he worked with two genes that was responsible for two distinct characters. Hence, in a cell that contains two genes responsible for two different characters in the organism, independent assortment will always occur during gamete formation. Although, in an organism that is homozygous for both traits (AABB or aabb), only one type of allelic combination will be produced in the gamete. However, the alleles will still randomly align and separate independently of one another during Metaphase and Anaphase stages of meiosis.
Answer:
Option (b).
Explanation:
Iguana and flying dragons are both reptiles. Iguana is a herbivorous lizard belongs to the order squamata. Flying dragons are known as gliding lizrds and belong to the genus<em> Draco. </em>
Iguana can easily be identified by their droopy skin, stocky stature and spines on their necks, backs, heads and tails. Iguanas may venture to the ground. Flying dragons has reduced tail, throat sacs color is different in males and females. Flying dragons used to live on trees, feed on the arboreal ants and will frequently venture in the ground.
Thus, the correct answer is option (B).

Answer:
All of the statements are true.
The X chromosome is one of the two sex chromosomes of humans and some animals (the other sex chromosome is the Y chromosome). Men have a single X chromosome and women two X chromosomes.
Diseases whose gene is localized on the X chromosome are most often transmitted in the X-linked recessive mode; some are transmitted on the dominant mode related to the X.
In this mode of inheritance, the morbid allele behaves like a recessive trait.
Women heterozygotes are not affected but can transmit the disease; they are aid to be conductive of the disease.
The disese is only manifested in male subjects (XY) with only one copy of the gene (hemizygous subjects)
