The proper order, from smallest to largest, for the levels of organization is
a. population, community, organism, biome, ecosystem, biosphere
b. organism, community, population, ecosystem, biome, biosphere
c. biosphere, biome, ecosystem, community, population, organism
d. organism, population, community, ecosystem, biome, biosphere
the proper order, from smallest to largest, for the levels of organization is
a. population, community, organism, biome, ecosystem, biosphere
b. organism, community, population, ecosystem, biome, biosphere
c. biosphere, biome, ecosystem, community, population, organism
d. organism, population, community, ecosystem, biome, biosphere

The right option is; d. organism, population, community, ecosystem, biome, biosphere

The proper order, from smallest to largest, for the levels of organization is; organism, population, community, ecosystem, biome, and biosphere. Organism (a discreet and complete living things; plants, animals or microorganism that has cellular structure and perform physiological functions) is the smallest, followed by population (group of organisms of similar species living in a certain area), community (which is composed of different species within a specific area), ecosystem (which is composed of all the communities in a certain area including biotic and abiotic), biome and biosphere.

white blood cells or wbc s are mainly 2 types-

1.agranulocytes

2.granulocytes

the monocytes or macrophages of agranulocytes , dendritic cells which are accessory leucocytes, and b cells which is one type of lymphocytes   identify the antigens present on the pathogen's surface. these three cells are called antigen presenting cells(apc) which are phagocytes and destroy the antigens by secreting antitoxins. besides this leukocyte is always plays vital role in the immunity of the body.

correct answer: understand the different control methods available

integrated pest management is an strategy that is based on the ecosystem and try to prevent the pest and the damage caused by them by applying combination of technique like habitat manipulation, biological control and use of resistant varieties.

the main aim of the integrated pest management is not to completely eliminate the pest but to strengthen the ecosystem so that conditions are favorable for plants and unfavorable for pests.
