The littoral zone of a lake is the near the shore area where sunlight penetrates all the way to the sediment and allows aquatic plants to grow. The benthic zone is the region at the lowest level of a body of a lake including the sediment surface and some sub-surface layers.
Terrestrial ecosystems refer to the ecosystems found on land, including forests, grasslands, deserts, and tundra. These ecosystems are characterized by the presence of plants and animals adapted to life on land, as opposed to aquatic ecosystems found in water bodies. Terrestrial ecosystems play a crucial role in supporting biodiversity, regulating climate, and providing resources for human beings.
Light determined the major types of flora and fauna found in aquatic ecosystems.eg, Tropical region compare to polar region. Due to presence of light, tropical is more productive than polar. so major flora and fauna are found in tropical, so light act as productive force in the tropical region.
Nitrosomonas bacteria convert ammonia into nitrites in the nitrification process, while Nitrobacter bacteria convert nitrites into nitrates. They are commonly found in soil and aquatic environments where ammonia is present, such as in wastewater treatment plants, soil with high nitrogen content, and aquatic ecosystems.
NATURAL ECOSYSTEM: an ecosystem made naturally & occurred naturally with no influence by man ( ex. forest, backyard) MAN-MADE ECOSYSTEM: an ecosystem with the influence of man, this is usually controlled ( ex. fishpond, zoo)
Plants commonly found around water ecosystems include cattails, water lilies, bulrushes, and aquatic grasses. These plants are adapted to thrive in wet conditions and play important roles in the health and balance of the ecosystem.
The Littoral Zone.
The three life zones found in aquatic lake habitats are the littoral zone, limnetic zone, and benthic zone. The littoral zone is the shallow area near the shore where sunlight penetrates, allowing for plant growth and supporting diverse wildlife. The limnetic zone is the open water area away from the shore, where phytoplankton and zooplankton thrive, serving as a crucial habitat for fish. The benthic zone refers to the bottom of the lake, where decomposers and detritivores break down organic matter, playing a vital role in nutrient cycling.
Phytoplanktons
I found these sand dollars in that littoral zone.
Diatoms are primarily classified into two main groups: centric diatoms and pennate diatoms. Centric diatoms are radially symmetrical and typically found in aquatic environments, while pennate diatoms are bilaterally symmetrical and often inhabit benthic or sedimentary environments. Both types are characterized by their siliceous cell walls, known as frustules, which contribute to their ecological role in aquatic ecosystems.
Plants can grow in the littoral zone of a lake due to the availability of sunlight, which penetrates this shallow area, promoting photosynthesis. The nutrient-rich sediments found at the bottom provide essential minerals and organic matter that support plant growth. Additionally, the calm waters of the littoral zone create a stable environment for various aquatic species, allowing diverse plant life to thrive. This zone also offers habitat and protection for aquatic organisms, further enhancing the ecosystem's productivity.

Algae are mostly found in aquatic environments such as oceans, lakes, and rivers. They can also be found in moist areas on land, such as rocks, soil, and tree bark. Algae play a crucial role in aquatic ecosystems by providing food and oxygen for other organisms.
Grassland and aquatic ecosystems differ primarily in their environmental conditions and dominant vegetation. Grasslands are characterized by open spaces filled with grasses and few trees, typically found in regions with moderate rainfall and seasonal climates. In contrast, aquatic ecosystems include freshwater (such as lakes and rivers) and marine environments (like oceans and seas), where the primary life forms are adapted to living in water. These ecosystems support diverse species of plants and animals that thrive in aquatic habitats.
Because they are designed to be isolated 'copies' of the natural environment that the fish and other aquatic creatures would be found in.
The freshwater zone that receives light all the way to the bottom is called the littoral zone. This area is typically found near the shore of lakes and ponds, where sunlight penetrates and supports a variety of aquatic plants and organisms. The presence of light in this zone allows for photosynthesis, making it a biologically productive region within freshwater ecosystems.
