Estuaries are bodies of water where freshwater from rivers meets and mixes with saltwater from the ocean. They provide important habitat for many fish and shellfish, with 2/3 of fish and shellfish species spending time in estuaries. Estuaries support complex food webs and nutrient cycles. However, they face threats from activities like dam construction, pollution from agriculture, and climate change, which can disrupt ecosystems. Conservation efforts aim to protect estuaries by restricting dams, reducing pollution, and regulating water use.
Coral bleaching occurs when coral polyps expel algae that live inside their tissues. Normally, coral polyps live in an endosymbiotic relationship with these algae, which are crucial for the health of the coral and the reef. The algae provides up to 90 percent of the coral's energy.
hen water is too warm, corals will expel the algae (zooxanthellae) living in their tissues causing the coral to turn completely white. This is called coral bleaching. When a coral bleaches, it is not dead. Corals can survive a bleaching event, but they are under more stress and are subject to mortality.
This presentation introduces two of the main threats that climate change poses to the survival of coral reefs: ocean acidification and bleaching events due to global warming.
Many fishers and aquaculturists are poor and ill-prepared to adapt to change, making them vulnerable to impacts on fish resources. Nature of the climate change threat. Fisheries and aquaculture are threatened by changes in temperature and, in freshwater ecosystems, precipitation. Storms may become more frequent and extreme, imperilling habitats, stocks, infrastructure and livelihoods.

Human life requires air, food, water and other materials for shelter, transport and varieties of socio-economic and life-support activities. Most of the required materials are available in raw or convertible forms on earth. These are the natural resources of the planet earth. This module give the basics of earth's natural resources.

Acetabularia Information For Class 9 .docxvaibhavrinwa19
Acetabularia acetabulum is a single-celled green alga that in its vegetative state is morphologically differentiated into a basal rhizoid and an axially elongated stalk, which bears whorls of branching hairs. The single diploid nucleus resides in the rhizoid.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

2. Facts about Estuary's Biome
• The estuary's are made up of fresh and salt
water.
• 2/3 of the fish and shellfish eat and spend
most of there time in the estuary’s
Estuary’s is a body of water surrounded by fresh
water and from river with salt water from the
ocean
Of the 32 largest cities 22 of are located on the
estuaries.
3. A biotic and Biotic factor of estuaries
biome
• The a biotic is water salt chemicals minerals
rocks air and sunshine
• The Biotic is Temperature Climate Biotic fish
Plankton Plants Phytoplankton
5. Definitions
Producer: is plant that makes its energy from the
sun
Primary Consumers: an animal that eats plants for
food.
Secondary Consumers A carnivore that eats
herbivore’s or plant eaters
Tertiary Consumers: the top animals of the food
web that eats other carnivores and herbivores
Decomposers: the animals that eats non-leaving
things that are found already dead
7. Dangers for this Biome
• Some Threats creation of dams disrupting
migrating routes for fish runoff from
agriculture and areas hurts water quality
draining water from the wet land over
population invasion of exotic species harm
native animals and plants global warming
8. Solutions
• Restrict the construction of dams
• Provide incentives for farming business to
reduce the use of pesticides
• Establish protect wetlands areas
• Regulate the with draw of water for human
use or don’t take lots of water from the wet
lands or fresh water lands
