Variety Of Organisms
Gbogbo ọrọ náà
Welcome to the fascinating world of Biology where we delve into the incredible diversity of organisms that inhabit our planet. The topic of 'Variety of Organisms' explores the rich tapestry of life across different kingdoms, each with its unique characteristics and adaptations.
Organisms are classified into various kingdoms based on their distinct features, ranging from the simple single-celled Monera such as bacteria and blue-green algae to the complex multicellular structures of the Animalia and Plantae kingdoms. Through this course, we aim to identify the diversity of organisms present in these kingdoms and understand the structural and functional adaptations that enable them to thrive in their respective environments.
One of the key objectives of this course is to describe how the structures, functions, and behaviors of organisms are intricately adapted to their environment and way of life. This involves exploring the fascinating world of adaptive coloration, where organisms evolve unique color patterns to blend in with their surroundings or to communicate specific warnings to predators or competitors.
Structural and functional adaptations play a crucial role in the survival of organisms. From the specialized beaks and legs of birds tailored for obtaining food to the intricate mouthparts of insects like mosquitoes and butterflies, each adaptation is honed through millions of years of evolution to suit a specific purpose.
Moreover, social animals such as termites exhibit different castes within their colonies, each with specific functions essential for the survival and thriving of the group. Understanding these intricate social structures and behaviors sheds light on the cooperative nature of some organisms in achieving common goals.
As we journey through this course, we will delve into the fascinating world of behavioral adaptations in animals, ranging from the territorial behavior of lizards to the intricate displays of feathers by birds in securing mates. These behaviors are not just random acts but are essential strategies for survival and reproduction.
Through a detailed exploration of the various kingdoms and their inhabitants, we will unravel the mysteries of life on Earth and gain a deeper appreciation for the incredible diversity of organisms and their adaptations. Join us on this scientific voyage as we uncover the wonders of the natural world!

Study specimens L and M and answer questions (a) to (e).
(a) Classify each of specimens L and M into its:
(i) Phylum L: ________ M: _______
(ii) Class L:_______ M:_______
(b)
(i) State three observable features of members of the class of specimen L.
(ii) Name three other classes of the phylum to which specimen L belongs.
(c)
(i) State two ways each by which specimens L and M are of economic importance. L: _______ M: ________
(ii) State five ways by which specimen L can be controlled.
(d)(i) State five observable differences between specimens L and M.
(ii) State four observable similarities between specimens L and M.
(e) Name one habitat each of specimens L and M. L:_______ M:_______
Akọwa Nkọwa
(a) Classification
| Specimen L (mosquito) | Specimen M (butterfly) | |
|---|---|---|
| (i) Phylum | Arthropoda | Arthropoda |
| (ii) Class | Insecta | Insecta |
(b)(i) Three observable features of the class Insecta: body divided into head, thorax and abdomen; three pairs of jointed walking legs; a pair of jointed antennae (also wings, compound eyes and a chitinous exoskeleton).
(b)(ii) Three other classes of Phylum Arthropoda: Crustacea, Arachnida and Chilopoda (or Diplopoda).
(c)(i) Two ways each is of economic importance
- L (mosquito): it is a vector that transmits diseases such as malaria, and its bites cause discomfort and disturb rest.
- M (butterfly): it pollinates flowers and has aesthetic (ornamental) value, though its larvae destroy crops such as citrus by feeding on them.
(c)(ii) Five ways specimen L (mosquito) can be controlled
- Removing all stagnant water around the house to prevent breeding.
- Pouring oil on stagnant water to suffocate the larvae and pupae.
- Spraying insecticides in and around the rooms to kill adult mosquitoes.
- Clearing bushes around the house to remove hiding and breeding places.
- Sleeping under treated mosquito nets to prevent bites.
(d)(i) Five observable differences between specimens L and M
| Specimen L (mosquito) | Specimen M (butterfly) |
|---|---|
| Small, slender body | Larger, broader body |
| One pair of narrow, transparent wings | Two pairs of broad wings covered with coloured scales |
| Dull greyish colour | Brightly coloured, patterned |
| Feathery (plumose) antennae | Clubbed antennae |
| Proboscis is slender and piercing | Proboscis is long and coiled for sucking nectar |
(d)(ii) Four observable similarities between L and M: both have the body in three divisions (head, thorax and abdomen); both have three pairs of legs and one pair of antennae; both possess wings and a pair of compound eyes; both have a chitinous exoskeleton and a proboscis for feeding.
(e) One habitat each: L (mosquito): damp, dark places near stagnant water. M (butterfly): gardens and grassland among flowering plants.

Which of the following is evidence of evolution?
Akọwa Nkọwa
All of the options listed are evidence of evolution.
Similarities in embryonic development:
Embryos of different organisms often have similar structures and developmental stages. For example, in the early stages of development, a human embryo has gill slits, similar to those of fish embryos. These similarities suggest a common evolutionary ancestry, where different organisms share common developmental patterns.
Fossils of extinct organisms:
Fossils provide direct evidence of organisms that once lived on Earth but are now extinct. By studying the preserved remains of ancient organisms, scientists can piece together the history and evolution of life. Fossilized bones, teeth, shells, and imprints of plants and animals provide a record of past life forms and how they have changed over time.
Homologous structures in different species:
Homologous structures are similar structures found in different species that originated from a common ancestor. For example, the forelimbs of a human, a bat, and a whale all have the same basic bone structure, even though they are used for different purposes. This similarity suggests that these species share a common ancestor and have evolved over time to adapt to their specific environments.
These different lines of evidence collectively support the theory of evolution, which states that all living organisms are related and have changed over time through a process of descent with modification.
