Are-created ecosystem in a laboratory environment is known as a
mesocosm
simulation
microcosm
reproduction

The correct answer is C. Microcosm

Explanation:

In biology and ecology, one of the techniques used to study ecosystem is the creation of artificial ecosystem or models of ecosystems that can be placed indoor in a laboratory or outdoor and are called microcosms, as they represent a larger and more complex ecosystem. Microcosms are considered as one important technique to study natural processes because they allow testing in a controlled way and without having effects on the real macro ecosystem. Therefore, a re-created ecosystem in a laboratory environment is a microcosm.

fertilization, pictured in figure 24.23a is the process in which gametes (an egg and sperm) fuse to form a zygote. the egg and sperm each contain one set of chromosomes. to ensure that the offspring has only one complete diploid set of chromosomes, only one sperm must fuse with one egg. in mammals, the egg is protected by a layer of extracellular matrix consisting mainly of glycoproteins called the zona pellucida. when a sperm binds to the zona pellucida, a series of biochemical events, called the acrosomal reactions, take place. in placental mammals, the acrosome contains digestive enzymes that initiate the degradation of the glycoprotein matrix protecting the egg and allowing the sperm plasma membrane to fuse with the egg plasma membrane, as illustrated in figure 24.23b. the fusion of these two membranes creates an opening through which the sperm nucleus is transferred into the ovum. the nuclear membranes of the egg and sperm break down and the two haploid genomes condense to form a diploid genome.
