We do not see all the varied functions that biodiversity plays in our lives because they are not obvious. We rarely see how they are controlling our environment unless we study nature. Thus we tend to take short-term actions that can have serious impacts on biodiversity leading to even extinction of species by disturbing their habitats. Man has no right to do so. We only share this planet with millions of other species that also have a right to survive on earth. It is morally wrong to allow man’s actions to lead to the extinction of species.

1. "*Sea otters are native to the western cosst of North America. Between 1750 and 1850 ,
hunting had reduced the population from hundreds of thousands to only one thousand
Individuals. In the early 1900 s, a small population of sea otters was discovered in Elkhorn
Slough, an estuary in central California near a large human population center. The otters were
then protected by the international fur seal treaty, which banned sea otter hunting. The sea otter
population has rebounded to nearly three thousand individuals today. Otters live in kelp forests
and eelgrass beds and feed on crabs and shellfish (Figure 1). Most herbivores in the habitat eat
algae that grows on the eelgrass and not the eelgrass itself. If there is too much algae, the
eelgrass does not receive enough light for photosynthesis. As the otter population has increased,
the eelgrass habitat has increased. Recently, however, scientists have noticed the presence of two
nonnative, predatory Invertebrate species that may be coloniaing the Elkhorn Slough, which
would have been too cold for them three decades ago. Scientists have also observed that otters in
the area are experiencing increased mortality because of an increase in harmful algal blooms,
which occur as a result of nutrient pollution. The harmful algae are ingested by shellfish, which
the otters eat. As otters were removed during the hunting years, there was a large decrease in the
catches of fish species from the eelgrass habitats. Which of the following best explains why this
decrease happened? a. Otters are a keystone species, so their disappearance from the area
affected the population size of one other species. b. Otters are a keystone species, so their
disappearance from the area resulted in the collapse of an entire community. c. Otters have
mutualistic relationships with many other specles, so thelr disappearance from the area affected
the population size of another species. d. Otters have mutualistic relationships with many other
species, so their disappearance from the area resulted in the collapse of an entire ecosystem. 2.

Hey friends,
This is from the chapter "Wildlife and resources". This chapter is from the geograpghy text book of CBSE. This is From the 10th standard syllabus.
Thank you.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

nearby Heron and Cormorant
colonies. This is one of the largest
colonies of these birds across
Europe. Data of the year is 2000, it

4. What led the herons to move their nesting from the Northern to the southern
juodkrantė? Historical sources tells us about their struggle with an
aggressive entrant in cormorants. Cormorants appeared in 1803. They
settled close to the herons and cormorants and Herons began to move the
cormorants' colony to Juodkrante. Herons were gradually moved to the
periphery. They began to migrate south of Juodkrante after 10 years under
two separate colonies of herons and cormorants on the northern edge of the
southern colonies and Juodkrante.
5. Cormorants and herons fighting
It is a strange fight between cormorants and herons. Cormorants have
moved their colony to the South near the herons. To 1978 Great cormorants
have been very rare in Lithuania, in the Curonian Lagoon, they're guests at
the seaside as well. Later in these areas from time to time, occur only
isolated birds, mostly in spring and autumn migration periods.
6. Another wave of the cormorants reached the Juodkrante in 1974-1978.
Gradually, the herons were forced to give up a significant part of their
nesting when, in 1995, when it's recorded the lowest amount of farming to
the herons.
Now, side by side, there are two colonies of herons and cormorants. In
2002, the accounting data was 500 pairs of herons and 2,000 pairs of
cormorant. Cormorants and herons are protected by the law.
7. In accordance with the requirements of this procedure describes the issue
of permits, in the territories of the fish farms in 2005, Hunter-style about
10,000 units. Cormorants. 2007-2013 the Ministry of finance, the cormorant

Cormorant colony chilled 10724 in five ovary. Ovary average in Lithuania –
3 eggs, a total of measures are dead in almost 32 thousand cormorants
progeny.
8. These measures have allowed to restrict the population recovered on the
big cormoran and spread. It features the same measures as adopted and
approved by 2010, the use of protected species description of procedure:

9. Cormorant droppings have killed all the pines, now dominated by shrubs or
