A1) A living being or an individual is known as an organism and it is a member of a species. A
species is a group of organisms that contains a set of specialized characteristics which distinguish
them from other organisms. The number of variety of species occurring in a community is
known as the species diversity. Species diversity has two important components-species richness
and species evenness. The species richness is the number of different species present in a
community. For example, a biological community like a coral reef contains large number of
species existing within the community and exhibits the high species richness. In contrast a forest
community containing limited number of specific plants exhibits low species richness. More
number of species present in an ecosystem represent its health because of the absence of factors
like nutrient depletion, competition, predation and extinction of species.
A2) New species arrive in habitat by geographical isolation and by immigration. The island
closer to the main land becomes a big source of immigration and have higher immigration rate
and contains higher species richness. The island distant from the main land has low immigration
rates because the species have to travel a lot to reach the island. Thus, these two factors influence
the species richness on the islands.
A3) A species chooses a specific habitat depending on availability of resources like nutrients and
other biotic factors. A diverse ecosystem with great variety of producer species producing more
plant biomass supports a great variety of a consumer species. The greater species richness in an
ecosystem makes it more productive, stable and sustainable. The greater species richness
promotes the food web and biotic interactions within the ecosystems resulting in greater
sustainability and enables to withstand the environmental disturbances like drought.
A4)
Native species are those that live in a specific ecosystem. Other species that migrate or
accidentally introduced in to another ecosystem are called as non native species or invasive or
exotic species.
The species that indicate or intimate the early warning of the damage to a community or an
ecosystem are known as indicator species. Birds are very good biological indicators as they can
predict the environmental changes rapidly.
The habitat loss by species is due to human activitites which introduce a species into a new
geographic location. For example, wild African honey bees known as killer bees were imported
to Brazil and caused damaged to native honey bees. Human activities like heavy utilization of
chemical pesticides is declining the populations of bird species. Butter flies are also good
indicator species as they are associated with several plant species making them vulnerable to
habitat loss and fragmentation due to heavy chemical fertilizers and pesticide usage. These
activities make the species to find new habitat to colonize and survive.

"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.

UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.
3. Wild Life and Food
• Wild animals exert significant influences on food production systems which may be
positive or negative. Positive influences include the role of wild animals as seed
dispersal and pollination agents as well as use of wild animal droppings as
fertilisers. Many species of birds and mammals such as bats, monkeys, baboons
and squirrels are known to spread fruit trees by their feeding action. A study in the
Cote d'Ivoire found that sites where elephants had vanished long ago lacked
saplings of certain tree species which are known to be dispersed by elephants
(Alexandra, 1978)
4. Agriculture and Wild Life
Historically, agricultural practices on public/ private land created many
different kinds of wildlife habitat. Odd areas, shelterbelts, hedgerows, and
fields in rotation provided havens for wildlife species that preferred
relatively undisturbed areas to rest, reproduce, and find protection from
predators or the weather.
5. Agriculture and Wild Life Contd
Cultivated fields offered food sources that
were important for many species, such as the
waste grain that fueled the long flights of
migratory birds. Some ground-nesting birds
built nests and raised young in cultivated
fields.
6. Agriculture and Wild Life Contd
Despite the adaptation of many wildlife
species to life on and around agricultural land,
wildlife and fish populations have declined
over much of the agricultural landscape in the
Umted States in recent decades. Many
individuals and organizations are concerned
about the future welfare of wildlife and fish
populations in the face of these declines
7. Wild Animals and Food Production System
Wild animals exert significant influences on
food production systems which may be
positive or negative. Positive influences
include the role of wild animals as seed
dispersal and pollination agents as well as use
of wild animal droppings as fertilizers. Many
species of birds and mammals such as bats,
monkeys, baboons and squirrels are known to
spread fruit trees by their feeding action
8. Wild Life Basic Components
All wildlife species require four basic
components: food, cover, water, and space. The
proper types, amounts, and arrangement of
these requirements vary among species. Species
utilize an area if supplied with the right types,
sufficient amounts, and proper arrangement of
these components at correct times of the year.
Properties that have an insufficient arrangement
or quantity of any one of these necessities will
not support a given wildlife species.

10. Wild Life Basic Components contd
one of these necessities will not support a
given wildlife species. The quality of food,
water, and cover can also influence the
survival and productivity of wildlife – higher
quality habitat will support a higher density of
animals. Decide what types of wildlife you
want to attract, determine which of their basic
four requirements could be improved on your
property, and then develop a plan to provide
these requirements
