An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life. Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts. … Abiotic factors include rocks, temperature, and humidity.
Is California's ecosystem highly productive?
California Current – Ecosystem The California Current Ecosystem (CCE) is a dynamic, diverse environment in the eastern North Pacific Ocean. … This highly productive coastal ecosystem is fueled by the seasonal upwelling of cold, nutrient-rich water.
Which ecosystem in California has the greatest diversity?
Even in their non-native dominated state, California’s grasslands are a tremendous diversity… One of the most dynamic California ecosystems is chaparral. Dominated by evergreen, SCLEROPHYLLOUS shrubs and small trees, chaparral is the most extensive vegetation type in the state (Figure 24.1).
What is the Mediterranean ecosystem like?
Mediterranean forests, woodlands, and scrub is a biome defined by the World Wide Fund for Nature. The biome is generally characterized by dry summers and rainy winters, although in some areas rainfall may be uniform. Summers are typically hot in low-lying inland locations but can be cool near colder seas.What ecosystem is San Diego?
The Mediterranean ecosystems of southern California are some of the most ecologically diverse systems outside of the tropics. The richness and diversity of plants and animals, as well as high rates of endemism, make the area a biodiversity hotspot.
What ecosystem is a desert?A desert ecosystem is defined by interactions between organisms, the climate in which they live, and any other non-living influences on the habitat. Deserts are arid regions that are generally associated with warm temperatures; however, cold deserts also exist.

Despite intense urban development, San Francisco still has significant areas of extraordinary natural ecosystems, including grasslands, wetlands, coastal scrub, dunes, woodlands, and, of course, the Bay and the Ocean. Coined in 1930, the word ecosystem means all the physical and biological components of an environment.
What are the 4 types of ecosystems?
The four ecosystem types are classifications known as artificial, terrestrial, lentic and lotic. Ecosystems are parts of biomes, which are climatic systems of life and organisms. In the biome’s ecosystems, there are living and nonliving environmental factors known as biotic and abiotic.

Does California have high or low ecosystem diversity?
California is a biodiversity hot spot because of its unique geography, climate, geologic history and size. California’s network of terrestrial protected lands covers 46% of the state. More than 30% of California’s species are threatened with extinction.
What type of soil is in California?
California Soil Types Since most California soils are a mixture of weathered rock, volcanic ash and plant residues, your soil will most likely be sandy, loamy, or claylike.
Why does California have such a diversity of species?
“Because California has so many unique and relatively young plant species, it was long assumed by biogeographers and naturalists that high speciation rates were the cause of California’s biodiversity,” Lancaster said.
What risks do humans pose to natural California ecosystems?
Direct pressures on ecosystems include urbanization, pollution, habitat encroachment, expansion of large-scale agriculture, strip mining and oil extraction, invasive alien species, road construction, livestock grazing, logging, increasing use of off-road vehicles, and suppression of natural fires.
What are examples of regulating ecosystem services?
A regulating service is the benefit provided by ecosystem processes that moderate natural phenomena. Regulating services include pollination, decomposition, water purification, erosion and flood control, and carbon storage and climate regulation.
How is California's climate?
Weather & Seasons Much of California has a Mediterranean-like climate with warm, dry summers and mild, wet winters. On the coast, the average daily high temperature hovers around 70°F and up, but can occasionally spike to 80°F or more on hottest summer days; freezing temperatures are rare, even in winter.

Why is San Diego so biodiverse?
San Diego in particular is considered a biodiversity hotspot. It has a large number of endemic species because of the varied topography and the unusual Mediterranean climate. It is the southern range limit of many northern species and the northern limit of many southern species.
Is California a Mediterranean climate?
The climate of California varies widely from hot desert to alpine tundra, depending on latitude, elevation, and proximity to the coast. California’s coastal regions, the Sierra Nevada foothills, and much of the Central Valley have a Mediterranean climate, with warmer, drier weather in summer and cooler, wetter weather …
